    AC Diagonostic Tune Up Center ST-200

    I hope to make this unit functional. I belong to a number of cars clubs, and there is always plenty of repairs that are needed. SO..... thanks again. Mike

    AC Diagonostic Tune Up Center ST-200

    INSP380, I really appreciate you posting this manual. I'll print it out and read it over. I'm sure it will help me getting this unit to work better. My machine is rougher than yours, pretty sure it serviced in a gas station for many years and got beat up. You show two operators manuals are they...

    AC Diagonostic Tune Up Center ST-200

    Still no luck with documentation. But, today I got the timing light to work. The xenon charge voltage was not working. One thing I noticed, this tool must be designed to work on 12 volt cars. I've been testing it on my 1939 Chevy and the 6 volt battery is marginal for lighting the neons...

    AC Diagonostic Tune Up Center ST-200

    Still no luck with documents, although I contacted a guy selling a ST-200 on eBay and asked if he would copy the manuals for my purchase. So far no response. Well, as far as the neon scale lamps go, today I found (after tracing wires) an oscillator on the battery voltage card that is used to...

    I found out that ACTRON acquired KAL Equipment. I emailed ACTRON and they responded but were no help. Here is the response. The item must have been made prior to our former owning company(SPX) acquiring KAL Equipment. We have no record of the tool at all. Unfortunately when KAL Equipment was...

    AC Diagonostic Tune Up Center ST-200

    Well.... still have not found any documentation for the ST-200. BUT... I opened up the battery connection module. It was a mess. The current shunt was broken off from the connection, there were broken wires, open wires and wires melted together. I also found that the high voltage leads were also...

    AC Diagonostic Tune Up Center ST-200

    No kill switch, at least that I can see (don't ask my wife if I can see). I've been looking for KAL and AC/GM equipment and documents. Looks like KAL was eaten up by another company some time ago and AC doesn't know anything about it, too old. I found a August 7, 1970 date inside. I've been...

    AC Diagonostic Tune Up Center ST-200

    I was just given this ST-200 meter box. The reason it was free is because when it is connected to an engine, the engine dies. SO.... I'm looking for any information on this unit I can find. I'd like a schematic and an owners manual. To date I got the voltage, dwell and RPM to work, but there...
