Thanks for the help Hanky.
I ran some tests today and here are the results.
Battery was bit low when I did the test. I did try to start using a good battery to no avail. I'm planning on getting a new battery in next couple of days. Asked the wife to bring me to get a new battery days ago since I have no wheels and I'm still waiting. I can't do the test you recommended until I get a new battery. Voltages read low on tests. Battery read about 12v at battery terminals and was dropping as I tested. The comparative differences in the lower 11v readings are fairly accurate even though the voltage was slowly dropping at the battery. (e.g. 11.36,11.18 and 11.5v were not due to a voltage drop from battery.)
Probing Detached ICM connector with positive lead of Multimeter. Negative to ground at distributor base. Key on/engine off except for start test #4.......
Ground #1 wire black/orange 4.5V This doesn't seem right. Short?
Coil wire #2 Green 11.36v
Run #3 Red 11.36v
start #4 zero and 11.18v with key in start and starter disabled
spout #5 11.5v
pip #6 3.96v
Again KOEO. Probing #1 terminal ground with negative lead of multimeter instead of red Reads 6.72V. It is a positive reading. There is no negative value indicating reverse polarity on the multimeter.
KOEO probing terminals with MM at coil with coil connected to harness.
Positive side using positive MM lead 10.82v
Negative side (green wire) again using positive MM lead 10.82v ???
Key Off and probing Green wire at coil with negative lead of MM 11.73v.
Ignition off. No run and no start. I get the following readings...
Negative lead of MM to all connector pins and positive to battery.
Ground Pin #1 11.89v
Coil #2 green 11.9v
Run/Power #3 11.9v
Start #4 11.9v
spout #5 11.38v
pip #6 11.11v
All terminals on Module connector seem to be grounded when ignition is off.
If I'm not mistaken there appears to be a short somewhere. Something's up with the ground terminal of the Ignition module connector reading 4.5v and 6.72v is it not?
I'm just learning here. Maybe you can point me in the right direction. If there is a short where would I start to look?
