voltage across battery when charging ?

Mustang_289 · 12-01-2005, 07:12 AM

PA Performance 3G 130A alt, got their wiring kit with the 200A inline fuse which runs to the starter selenoid. Battery is located in the back hatch with a Morosso relocation kit, which has a 2G wire going from the starter selenoid back to the positive on battery. Negative from battery runs to a shut off switch, which is grounded to the frame in the rear. Up front, we've got an engine to frame ground, and an engine to firewall ground with the strap.

Is there a quick and easy way to check for shorts in the system?

Sounds like a short to me. If you disconnect the battery, all of a sudden it's putting out the correct voltage at the starter solenoid. That eliminates the alt. and ITS wiring right there.

Not familiar with the PAP unit, is it internally regulated, or do you have an external regulator on that? I had that exact problem, and figured out my external regulator wasn't wired correctly. Fixed that, and buddah bing, 14volts at the battery in my hatch.
