Rovac and Gateway have teamed efforts to provide the latest news and information for the mechanic and the industry at large. Information contanied in this publication are written by mechanics for mechanics. Here is the present line-up of features we plan to cover every two weeks. 1> This Weeks Coverage - Contents, with page #s per story 2> Mechanics Newswire: Shorts on industry news. 3> Feature Articles: 4> Mechanic's Help Column: 5> Mechanics Information Network News: 6> Guest Commentary: We will be organizing the TSB database according to the following categories. In considering ideas to write about, think about the categories listed below: Product/Service Categories: =========================== Catagory Description ======== ===================================== A1 Identification, Models, Etc. A2 Chemicals, Antifreeze, Additives A3 Tools, Equipment A Labor Times, Manuals, Aids B Wheels, Tires, Wheel Bearings, Seals C Brakes, Including Power Brakes D Steering, Suspension E Drive Axles, Drive Shafts, U-Joints F Manual Transmissions, Clutches G Automatic Transmissions, Coolers H Diesel Engines I Gasoline Engines J Ignition, Including Electronic Ignition K Fuel System, Filters (Air and Fuel), Etc. L Exhaust System M Cooling System, Water Pump, Drive Belts N Emission Controls, (includes Catalytic Converters) O Starting, Charging, Battery P Lighting, Horns, Turn Signals, Etc. Q Instruments, Dash Cluster, Controls, Mirrors R Chassis Electrical, Wiring Harness, Fuses, Circuit Breakers, Wipers, Widow Motors S Auxiliary Equipment, Jacks, Trailer Hitches T Heating, Air Conditioning, Ventilation U Electronic Devices, Stereo, Radio, Etc. V Entertainment Devices, Stereo, Radio, Etc. W Seats, Belts, Interior Trim, Carpets, Etc. X Glass, Doors, Hood, Decklid, Tailgate, Liftgate Y Finishes, Body Structure, Frame, Bumpers Z Seals, Gaskets, Sealants Our editorial philosophy is be to make this magazine the voice of the mechanic. Few mechanics have the opportunity to broadcast their opinion, and those who do are usually tied to the leash of editors, publishers, and advertisers. We are here to provide the forum for discussion of problem service applications, applications which may not yet be covered by factory technical service bulletins. Discussions here could facilitate the development of early solutions. Discussion here will also flush out the availability of good information sources and product resources for improving the productivity of the professional mechanic. A few such sources are discussed below. !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! MECHANICS NEWSWIRE :::::::::::::::::::::::::::::::::::::::::::::::::::: ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: MARCH MOTOR SERVICE: Ctsy CompuServe Atari Forums #: 28751 S8/Hot Topics 25-Mar-90 17:43:15 Sb: Atari Exposure? Fm: Peter J. Joseph 71540,3347 Hello Atarians, Anybody out there have access to automotive service departments? If so, check out the March issue of Motor Service. The cover story is about computer systems in the service department and the COVER photo is nothing other than an ST! How about that. The catch? Of all the systems mentioned in the article, none are the Atari. Guess they just liked the picture. Oh well, it was nice to see it 'advertized' just the same. BTW, there was also an ad inside for anoth system that pictured an ST style mouse with someone else's name on it. Is Atari selling to third party hardware mfrs? Enough for now. *********************************************************************** INDEPENDENT MECHANICS ACCESS FACTORY TECH SERVICE BULLETINS *********************************************************************** A little known fact, sometimes received in the context of "unbelievable", is that a complete library of all factory issued technical service bulletins is available, published as they appear, for all mechanics, not just authorized dealer mechanics. These bulletins appear in part in prominent services offered by the manual companies, such as Mitchell, Motor, Chilton. There is a lag time to do the publishing cycle, and some bulletins are not published in the manuals because of space limitations. Companies such as Mitchell and Alldata offer manuals and Technical Service Bulletins on CD-ROM discs loaded with tens of thousands of pages of information per disc, readable through the CD-ROM reader/interface by a conventional computer. Alldata goes so far as to provide a built-in printer in its computer, and eliminates the keyboard, substituting a mouse as the interface for selecting information from the massive database. Autotext, a firm in Pennsylvania has been ten years and 27,000 hours of computer time in the making. It was the dream of a former editor of Motor Age Magazine, Gerry Haddon. Piecing availability a dealer at a time, Gerry enlisted a network of dealers from American Motors to Volvo, to secure a consistent flow of bulletins as soon as they became available. The bulletins were cataloged and indexed for quick retrieval. Today Autotext provides the raw data for many leading information sources in the aftermarket. The information is available in hardcopy subscription by mail under the TECFACTS program. These service bulletins are selected by product category and used by many parts manufacturer answerman and tech service departments as a key reference resource. Selected by make of vehicle, the bulletins serve independent repair specialists for the specific automobiles they concentrate on. For systems service specialists, the bulletins can be selected as they are by the parts manufacturers, using the parts/systems categories... brakes, electronics, fuel system, filters, heating, etc. The categories are listed above. The bulletins are also available in the cost effective microfiche format, as a compact, durable reference resource. Having the right bulletin at the right time can be a real time saver and profit improver. According to one Alldata sales brochure, the right bulletin on a Cadillac Eldorado suffering from an intermittent connection could save 8 hours of trouble shooting with a scope which was unable to detect the problem. Information covering Technical Service Bulletins is available from Autotext, Leary RD RD#2, Honey Brook PA 19344%Ph 215-273-2926. Mitchell Manuals, POB 26260, San Diego CA 92126%Ph 800/854-7030. AllData Corp., 9412 Big Horn Blvd., Elk Grove CA 95758% 800/666-8008. *********************************************************************** MECHANIC'S INFORMATION NETWORK FLUSHES OUT FIXES *********************************************************************** Any large base of information is difficult for one person to know. A group of dedicated professionals can help each other sort through the information jungle and flag key answers. To facilitate the broad availability of TSB's for the mechanic, Autotext has made available its list of bulletins. It is our intention to post selections of the bulletin listings in Library 16 of the The Racing Information Network reached by GO RACING on Compuserve. Mike Hollander has generously offered an area in Motoring Topics for mechanics to meet and discuss the resource. Ron Kovacs of Z*Net, an electronic newsletter publisher, will be organizing information and summaries for easy download from the Compuserve Library. We are intent on developing a summary database covering the service bulletins. A four line extract will cover the bulletin, and provide all the information needed to finish the service job expeditiously in 80% of the cases. In the cases where the summarized bulletins are not adequate, the suggestion to refer to the full bulletin will be listed. The database would be searchable in much the same way PCExpert works. Three or four key words cull out the 5 to a dozen related bulletin summaries. From these the mechanic can select the specific bulletin which relates to the job. If we develop good traffic by identifying professional mechanics within the 500,000 members of Compuserve, and motivating them to visit the Racing/Motoring Topics/MechInfoNet message bases, and download Library 16, to prove the interest, we will then develop the resource to make service bulletin search a quick and valuable online service. Hard copies of bulletins in their full and graphic form are available individually by mail, subscription, or fax. Typical bulletins are two or three pages complete, and cost about $1 per page under current promotional pricing. Fax machines are everywhere today...in typing services, at quick print shops, in libraries, and at post offices. Inexpensive fax machines are available below $400. Fax boards allowing computers to download and store faxes to memory or disk or hard drive are available for as little as $199. If you would like to receive literature covering the TSB service, please post your address under private e-mail to Gateway Associates @ 72327,1500 here on Compuserve. Gateway will consolidate and forward the requests for information. *********************************************************************** FOUNDING MEMBERS COULD SERVE AS M.O.N EDITORS *********************************************************************** Listed below are many of the Compuserve users here who have expressed an interest in supporting the development of a mechanic's information exchange here on Compuserve.

Notes for story subjects: Using cordless phone for improved productivity *********************************************************************** COMPUTER DIAGNOSTICS *********************************************************************** Our first story submission is from a respected associate from Kansas, formerly from Rhode Island, where he managed a Garrett Turbocharger distributorship. I have followed Eric to Kansas and have maintained contact, anticipating the MechInfoNet project. I think you will enjoy what he has to say. MIDWAY DEVELOPMENT Automotive Engineering Research-Development Consulting-Application (316)455-2434 Rural Route 3, Box 33A, Udall, Kansas 67146 COMPUTER DIAGNOSTICS Can the small shop survive? Automotive computer diagnostics became a reality in 1980. Now, in 1990, the ability to properly diagnose and repair the automotive ECU, has become a necessity. In addition to the ECU, is the sensors, wire harnesses, connections, and parameters involved in making the system operate correctly. The days of bypassing a system to regain engine performance are gone. Bypass one of todays systems, and the car may not run at all, never mind perform! Catch 22 has arrived, in force. So, just how does the small 2 or 3 man shop compete? Simple really. First, dont be afraid to tell your customer that it's going to cost money to fix. Most cars that are coming to your shop are long out of warranty by now, and chances are real good that your shops labor rate is alot less expensive than the dealership. Usually 1 hour is enough to diagnose all but the most difficult of cases, provided the shop has a technician capable of reading a diagnostic chart, and that the shop has a few simple tools. So, just what does the shop need? Although every equipment salesman will insist that it can't be done without his top of the line machine it can be done with some simple tools, and a manual. The two top diagnostic computers on the market, for my money, are the Sun MCA, and the Sun Interrogator II. These machines incorporate the best of available technology, in an easy to use format, with the ability to run computer diagnostics and an engine analyzer simultaneousley. Of course, these machines are also expensive, starting between $22,000 and about $28,000, depending on options. Can a 2 or 3 man shop afford one? Probably not. So, the answer must be in the inexpensive hand tools and manuals, I mentioned before. First the manuals. While the factory manuals may seem like the ultimate answer, often the factory books make reference to tools or other manuals not always available to a small shop. If the special tools or books are not available to you, the manual is also worthless, as they don't usually give an alternative test. So the best answer is a manual written for the small shop. Mitchell is a publisher based in California, who writes off the shelf manuals for automotive service professionals. The manuals they write are used by the diagnostic machine companies, when programming the big machines. Therefore these manuals are the most logical ones to use. So, 1st a technician, 2nd the manuals needed to diagnose, 3rd the special tools. Wait! Didn't I say inexpensive tools? Yup, but sort of special just the same. First, a digital volt/ohm meter. It does not have to be a real expensive one, but it must be capable of indicating in the milivolt scale, with ohmmeter capability in the 0 to 20,000 ohm scale. Most sensors today read in tenth's of a volt, and resistances for some sensors range as high 18,000 ohms. A few sensors run higher resistances on the upper end of the scale, but by testing at the low end, and the middle, you can guess pretty close if it's within tolerances. Second an analog type volt/ohm meter. Some manufacturers tests include time duration tests when reading computer faults, and a digital meter responds too fast to accurately read duration. Third, a simple test light, like we've always used on electrical problems, to make continuity tests. A few test leads, of lenghts ranging from 1 foot to 10 feet, and our tool inventory is complete! With the tools I've described, and the ability to follow the charts, computer diagnostics is within reach. Remember to follow the charts religiously, one missed step could mean a missed problem, and a week long nightmare! Always remember that its a machine before a computer, so all mechanical systems should be checked first! A leaky valve, or jumped timing belt, can cause the same symptoms, as a faulty sensor, or burned out ECU. Ignition wires, cap and rotor, and spark plugs, all do the same job they've done since the beginning, computers have only improved the efficiency, not the basic operation. The distribtorless ignition merely replaced the distributor, with a crankshaft location sensor, and more ignition coils. This system does the same job a distributor does, only with less moving parts. As a parting word, I'd like to mention the little brothers to the diagnostic computer, the hand held portable. While not as capable as their shop bound bigger brothers, there are distinct advantages to these small portable units. The ability to take it on the road is the biggest. Some intermittant problems can be impossible to duplicate in the shop, and therein lies the advantage. However, be careful if your considering purchasing one, some manufacturers claim more than the machine can deliver. If the machine can't do what you need, why buy it? Test it out BEFORE you buy it!
