Barracuda No-Start

Recheck your wiring carefully and DISCONNECT YOUR tach if you have one. You should only have two wires (for testing) hooked to the coil......the one going from the ECU to coil NEG, and the one coming from the ballast, supplying voltage. If you have a "dual" ballast make sure both sides are good. This is two resistors hooked together

Check coil and ballast voltage.

With key in "run" and everything connected "normally" you should have "same as battery" at "key" side of ballast, (about 12-12.6) and about 6--9 or so at coil POS. Coil NEG should be quite low, perhaps 1/2--1 volt.

Connect meter to coil POS and crank the engine USING THE KEY. You should have "same as battery" while cranking or about 10.5V or higher. Compare to battery PLUS while cranking
