Fire to the HEI coil but none coming out

[Faster Eddie]

Once she warmed up it just died.

Changed the coil pack, and the ignition module but still nothing.

Any advice for chasing this one down?

Got 12 volts going into the coil and nothing coming out

Voltage drops from 11 in On position to 8 in start

Is it an older HEI with a lot of use on it? Ck the two small wires coming from the pick up coil, one is green typically and I tick the other is white. The can become broken at the terminal from moving with the advance plate.

It's brand new. Don't see anything obvious at all. So 514 are you saying I need to pull the dizzy, tear it apart down low and inspect?

 

[Faster Eddie]

Update! The tach wire was grounding out under the dash which killed all spark.

Hate it when that happens...

Glad you got it figured out.
