Tested the coil, cold it is 2 ohms, current starts at 6.5 amp and rises. Coil gets to hot to touch, current at 10.5 amp, resistance is 1.4 ohm. Using a 12 volt battery as a supply. Both coils do this, the new one and the old one. If I run at 8 volts everything stays stable, So now, does the coil req...

Thank you for all the responses. We'll have to do some additional testing. I'm going to put 12 volts to coil I took out and see what the results are. I'm also going to watch the current in the current coil as it goes up turn the car off and then turn it back on to see if it time-critical. I also hav...

Thanks for the reply, but I have to disagree, dirty connector means less current as the voltage will drop across the connector. If coil has the same inductance, with less voltage, that's less power

Have 07 Uplander that blows the air conditioner fuse after about 10 minutes. I watch with an ammeter is the current went from about 8 amps to 12 amps over 10 min. Slowly climbing. I replace the AC coil and the unit and the fuse last much longer but still with the same results of a blown fuse. Even i...
