The ancient Sun tach taken from the steering column of my ' 61 Dodge Dart installed neatly on the column of a '63 D100. The Dart had point ignition the truck a new Mopar Electronic Ignition. The truck ran great until I added the tach, now it just quits making ignition after 10 minutes. Just flat stops! Unhook the tach and it is good to go again. Anybody know how I can have the old tach and the new ignition work in harmony? Larry Jett |
