Bought the msd tach adapter for my x7 cressida , hooked it up, fired my car for the first time worked perfectly....

Noitced alternator wasnt holding a charge so checked the wiring, its ok so i assume its shit and got a new one.

Slapped a new one in and now my damn tach is either going ballistic or not working at all. Checked wiring and everything

else like that and its fine....





any other suggestions?
