I have an oliver 77 that has been giving me problems with a tachometer. It has an autometer tach that is hooked up to the coil. It worked fine for about two weeks and now reads erratic and often times double. I pulled it out to make sure the cylinder selection switch was on 6cy and it was. Also, I have a timing light that measures RPM, It was used initially to set RPM on the tractor and when I tried it yesterday it was erratic as well and would read 4000-6000 at idle. I took the gun to my brothers tractor and it worked fine.
On my tractor I have non resistor Auto Lite 3116, solid copper core wires, and an alternator. I'm just not sure why the electronics are acting this way. The tractor runs fine itself, just my electronic instruments won't work. Any suggestions?
