Wiring help for trunk mount battery

You may have lost the voltage regulator, especially if it was an original. Melting down the ford solenoid may not have done it any favors.

My original VR checked out not too long after I went to my new 100 amp alternator. I replaced it with new on and haven’t had any issues since.

I tried 3 different voltage regulators all with the same outcome, way overcharging. I have almost 0 voltage drop from ground wire at the block to the Voltage regulator case. I have about a .2 volt drop from output sensor wire from the ignition bulkhead wire to positive side of the battery. I'm pretty sure the alternator let go. Its a reman unit from autozone about 2 years old. unless my one year old AGM battery is bad but it cranks over fine.
