I popped it off the fire wall and swapped on a used one. Does it need to be grounded? The battery was pretty dead this morning. I jumped it and checked the voltage. It wasn't charging. I have it hanging out in case I need to swap on a new one. "The only thing to do for triumph of evil is for good men to do nothing" "NUNQUAM NON PARATUS!"

Connect the case to ground with a jumper wire with alligator clips and it if it now charges, bolt it down (clean under the holes) and you're set live every 24 hour block of time like it's your last day on earth

Fired it up, turned on the head light for 10 minutes with it running. The meter said 13.4. I have been to Nashville and back. Everything is fine.

The OE Mopar regulators are powdered-coated and/or painted on the back side preventing a solid ground connection. Just my $0.02..

I do the same and I like to run a braided groundstrap from one of the mounting bolts/screws to the engine as well. Steve
