Snap-on Engine analyzers

Recommended Posts

A couple of years ago I purchased a carburetor and ignition business. With this acquisition came a lot of junk, including 2 Snap-on engine analyzers. One is a Counselor XL (model MT 1765), the other is a Counselor MT 1665. I cleaned them up and brought them to my shop. They both turn on and the functions can be brought up on the screen and I would guess they are in good shape. My question is, will they work on 6-volt cars? There is nothing in the manual refering to 6 or 12 volt systems and there is not a switch or button on the units for 6 or 12 volts.

I had a Sun analyzer similar to what you have. There is no 6/12 volt mode, per se. The voltmeter doesn't care. In fact it will tell you. Same for the amps. Vacuum is vacuum. Exhaust is exhaust, dwell is dwell, etc. The ignition analyzer is triggered by the spark, so it doesn't care where the spark came from. 6 or 12 volt. Have fun with your new toy.......Bob
