Ok so made time today. I had a spare coil hooked up, laying on top of 1st one. I noticed the spare was leaking some oil.
Did ohm test on both coils. Leaky one primary was 1.4 ohms. 2ndary was 8900 ohms. Checked 1st initial coil, 1.6 ohms primary. 2ndary 8650 ohms.
Hooked initial one back up.
Static batt voltage 13.1 V
Swapped spare used ecu from 84 D150.
Fired right up.
Battery volt at idle 13.5v
Alternator stud to ground 13.8v.
I realize I didnt run all your tests del. Ran outta time today. I will get more results.
I rev in park voltmeter climbs to 15V and drops with rpms.
