Flakey Tach

Recommended Posts

I'm having some issues with the tach in my 74' 260 (Carborated L28 engine) The car itself starts (if I can ever track down why my battery keeps draining, maybe reliably someday) and runs fine, but my tach doesn't work. When the car is off the needle goes to the rest loaction on the guage, but when you start it the needle goes all the way right. I've seen it work once for a few minutes then it just went to the right again. Any ideas?

Thanks

Check the feed wire from the coil. If that doesn't do it, then it probably is a burnt out tach.

There's a small resistor between the lower circuit board and the upper circuit board, if this starts going you'll get that kind of result.

Sorry.
