Electric issue with winch on log arch

I have continuity across these post. I'm thinking that would be a dead short wouldnt it?

It's only going to be about 3 or 4 ohms when it's ok. It would look like a dead short depending on how you're checking it. You need a meter that will read low ohms (most will).

I tested across the terminals. 1.2 ohms

What is the problem? What is happening when you connect 12VDC?

That could be correct depending on the rated power of the motor. MM's question is the next step.

It was making my lights come on on my tractor when I hit the switch. Like it was back feeding

What are you tied into on your tractor with your supply wires?

Straight to the battery

Is your tractor positive or negative ground?

Ljohnsaw · March 21, 2020, 03:13:36 PM

Also, assuming this is with the arch attached to the tractor. Have you tried it with it not attached? Results?

Kwill · March 21, 2020, 03:21:16 PM

Negative ground

donbj · March 21, 2020, 03:47:49 PM

Are you fully hard wired to the battery or using the arch hitch as ground connection?

Turns out some cobbled up wiring that had something to do with the volt meter off the negative side of the battery was causing issues. Took that off and no volt meter now but the winch works fine. Always something. Wasted somr of this nice day jacking around when I should of had a trailer full of logs

might have been and amp meter if it had a flat bar "shunt" for measuring current on the negative side of the battery.

Always Something is right. As long as we want to use equipment, new, old, home built, it will always be something. Some days it is better than others for sure.
