12v portable winch problem

Question

I have a 12v portable winch that worked just fine last Fall. It is always stored inside, Now when I hook it to a battery the 2 relays just click, the motor won't run. When hooked directly to the battery the motor runs. I bypassed the thermal cutout switch, replaced both relays, bypassed the switch on the remote control, tried 3 different batteries. Still won't run. Does anyone have a suggestion?

If it runs directly from battery, you've almost eliminated the motor being the problem. I wonder why then you tried 3 different batteries. And you have nearly eliminated everything else.
If what you say is accurate, it is near impossible.
The problem could be found in a minute or less w/ a 12v test lite.
Do you own one ? If not, get one !

I've had the contactors inside the chintzy remote control handle not work. I can't remember how I fixed it, or what the problem was, but it involved taking the control apart several times and much frustration.

RJsfishin, I tried 3 batteries because it appears to be a low voltage problem. Even though a battery might give good voltage readings that doesn't mean it's ok. I'm using a Fluke vom to test.

Brian, I've checked the resistance through the remote switch and bypassed the remote switch.

Thanks to both of you for your reply.

The relays are clicking...are they making contact inside?

mthockey dad, I just found the problem in the socket where the remote control plugs in. Half of one contact was smashed down bridging it to another contact. I straightened it out and everything is fine.

Thanks to everyone for your comments.
