No spark Mopar dizzy and FBO box & coil

gtsdude said

I did have 11.5v or so at + and -sides of coil with key in run position, makes me lean toward ECU,

NOTE I could be incorrect on this, here's why.

NORMAL Mopar ECU draws coil current (coil NEG is grounded) with key on / not running)

GM HEI IS NOT. That is coil does not get warm with GM HEI key on / engine stopped

SINCE this is FBO and not "Mopar" I don't know, after some thought, whether they do or do not draw current
