Tach is going crazy!!! Help
I put a sunpro tach on my 72 cheyenne, and whenever i turn on the fan or headlights or anything electrical, my tach starts going crazy. I have a mallory distributor with the green wire hooked up to it. I have it grounded to the battery, which is better than grounding it under the dash where it was. Any suggestions would be appreciated.
