Guest Anonymous Posted January 12, 2001 Share Posted January 12, 2001 Does the tach on an early 260 run off the positive or negative contact on the coil? My tach is pegged on the high side whenever the ignition is on. Sometimes several minutes of operation it will start working. Is the tach broken or bad contacts? The ballast resister has 3 contacts, if the tach is off the positive contact of the coil is the tach connected to the ballast resister? Any help on tach operation is appreciated.

rags Posted January 14, 2001 Share Posted January 14, 2001 Are you still going through the little electronic ignition box in the passanger foot well? I had to bypass mine to get my tach to work. And yes, it does hook up to the neg side of the coil. Joe Quote Link to comment Share on other sites More sharing options...
