The plow is using the truck battery which is connected right to the alternator. The dump trailer battery is only connected by a small wire with a 25 amp fuse. Itís not a high charging wire. I think my issue may have been more the battery than anything. But Iím still thinking about a heavier wire in case I run into that problem again. At least itís gravity down.

were it me, and you're using that dump repeatedly during the day....run a 4 ott..how the hell you spell that...welder cable from battery to battery. that way the pickup battery can help while it's hoisting.

can't believe it would never keep up.

Negative.

The current will split in parallel circuits, proportional to resistance. For a variety of reasons, it's not a good idea to have 2 different wire sizes in parallel.

What variety would that be?

The current will follow the path of least resistance. It makes absolutely no difference if you leave the original charging wire connected.

I have a 270 amp alternator on my truck. I run 4ō cable to the batteries and have the factory lead connected also.

I'll give you a beginners lesson in electrical theory later. Kinda busy right now. :blink: :jester:

Inform me, I know nothing of electricity.

I've had a charge wire on my dump trailer since I built it 8 years ago and have never had any issues. I don't dump on a regular basis but it's never let me down.
