92 Dodge Caravan Strange Voltage issue.
I'm new to the DF. I have a 92 Dodge Caravan witht the 3.3l. My voltage is reading low with the van running. 12.3v. I have put a new alt on it, done the voltage regulator bypass kit and still have the same voltage reading of 12.3-12.5v with the van running. The resting voltage of the battery is 12.9-13.1v van off. If I use a 2nd battery that is not tied to the vans electrical, I get 14.5v with the van running. Basically running a charging wire from the alt to the 2nd batt only and the 12+ from the regulator. Any help or info would be greatly appreciated. Thanks.

The battery terminals good. The battery has threaded post. I have narrowed it done to the 3 wires that is in the fusable link. 2 are solid red and the other is red/white. These 3 wires have to be connected to 12+ for the van to run. However i cant tell what else is all connected to these 3 wires. I do know that the R/W goes to 2 of the relays on the fender. The solid red goes to one of those relays also. It almost seems that i have a short to ground somewhere. But I would think if there is a short something blow or burn up.

Yep, I remember those. We don't see that generation at all anymore, but it's what I started out on in 92 when I hit the door. What will throw you is the links will blow but the insulation on the outside can still look perfectly intact. Just get a good test light and work your way from one end to the other at different spots and you will find it. Maybe like every 2 or 3 inches.

Should be less than 5. Less than 2 really. Make sure to have any wire you're checking for resistance disconnected from it's termination at both ends.
