Winch wiring question

[Magikal]

Warn x8000i with in cab controls. All works fine but i recently burned up the motor. I bought an aftermarket one online and went with the heavy duty with thermal overload protection. Didn't realize until recieving it that the thermal overload is two more wires coming from the motor. I understand that it is a closed circuit that opens up when it gets hot. That's fine, I'll patch it inline to my master arm switch in the cab.

My question is how can i wire in an indicator light that goes on when the thermal protection cuts the power and off when all is well?

Use the normally ON side of a relay for the light. Power the relay with the thermal circuit. When the thermal circuit puts power to the relay it will shut the light OFF, when the thermal trips it will cut power to the relay and the light will come ON. Run the light power from the master switch to keep the light from draining the battery when not using the winch.

How is the relay going to turn the light off by recieving power from the thermal?

Sketch me a schematic. I'm very much a hands on/visual learner...

A relay has 2 sides to it. One that is OFF and becomes ON when you power the control circuit. At the same time the other side of the relay is ON and becomes OFF when you power the control circuit. I will see if I can find a diagram.

So 87 gets power when the switch is ON in this picture. 87a has power UNTIL the switch is on. Instead of the switch you would power the relay with the thermal circuit. Usually when we are all hooking up lights or fans to relays we are ignoring the existence of 87a and just using terminal 87.

 

[Magikal]

So as long as 86 has power, 87a won't close the circuit? If so, i got. I understand basic relays but never messed with 87a. Guess I'll grab my multimeter and confirm.... (hands on learner ya know)

Yep, 86 is the on/off coil wire, little electromagnet inside flipping back and forth from 87 to 87a. 87 is always the opposite of 87a.

I had a friend pick up a railroad crossing signal light for outside his coffee shop. He wanted to have it flash left, right, left, right like at the railroad crossing. He couldn't figure it out until we explored this same relay diagram. Hooked 1 light up to 87 and the other to 87a and instead of constant power to 86 we hooked it to a flasher unit. Flashes back and forth now just like at the railroad crossing.

Thanx. I think i got it under control now. Appreciate the assistance.

Something like this. Never mind beyond the dpdt switch. That's all under control. Just focused on the relay set up.
