Starter solenoid capabilities.

[tw205]

I got a 9000 Warn winch in barter for some labor. I’ve never had one so I’ve no knowledge of how they are generally wired in. I didn’t want it powered all the time so here’s what I did. I dug out an old starter solenoid and mounted it next to the one on the fender well. I then took a short battery type cable and jumped power from solenoid to solenoid. I attached the + power cable from the winch to the starter side of the newly added solenoid. Then I used a 12v wire from a switch in the cab to activate the solenoid. Giving me the ability to isolate the power to the winch. Worked great for a while but eventually quit. 12v on the s terminal would no longer activate the solenoid. So my question is, does constant power on the s terminal of the solenoid cause failure or was my solenoid just old and worn out? Solenoid is dirt cheap but don’t want to just throw money away.
Thanks y’all.

Those starter solenoids (relay) are not for continuous use. They are designed for momentary activation. You really need a continuous use relay.

Look for Golf Cart 100 or 150amp 12v relays they are designed for continuous duty

The coil in a Starter Relay is not designed for continuous duty so heats up and fails over time

That was my suspicion. Thanks.

anks. That’s was my suspicion. Thanks for the reference info on the relays.
