Help me wire a switch to replace my remote on my winch

[sofasurfer]

I have a Chicago Electric winch from Harbor Freight. the remote receiver is not working. I'm assuming it is bad. I want to (ideally) fix the remote receiver. I have power to the receiver but thats all I know.

Assuming the receiver is non-fixable I want to wire a switch to the control box to operate the winch. I can just jump power directly to the winch motor but don't know if thats a good idea, thus the desire to wire to the control box. The control box includes the remote receiver and the 2 relays, thats all. Any help is appreciated.

Is this a wired or wireless remote?
Could it be batteries in the remote?

Wireless remote. New battery. The led in the remote lights up.

800 444 3353 HF number for parts. Google model number for the manual parts list and exploded view is in there.

Have you done any basic wiring/ power checks?

^^ X2 . have you confirmed that the motor is good?

Using multimeter I have 12v across "R" and "BK" terminals of remote receiver (see schematic in post #1). I didn't get anything at the other 2 terminals. I removed the relays and put voltage across terminals 85 and 86 and the relays clicked.

Motor does work with 12v from battery.

The remote receiver is essentially getting constant power and ground/common and then when the fwd button is pressed on the remote it is engaging one relay for normal polarity output to the motor, when the reverse button is pressed, it is engaging the other relay to reverse the polarity feeding the motor to allow the motor to run in reverse.

If you want to do away with the remote receiver, all you would have to do is wire 2 switches from 12VDC+ constant to the + terminals of each coil of reach relay. One switch would enable fwd operation of the motor and the other rev operation of the motor.

Per your diagram, terminal 87 appears to be 12VDC+ constant and terminals 85 and 86 appear to be your 12VDC+ coil voltage inputs for the relays.

If you jumper 87 to 85, does the relay engage and run the motor in one direction and if you engage 87 to 86 does the other relay engage and run the motor the other direction?

If jumpering these terminals does not work, the relays likely need replacement as they may not be internally making a good connection to feed power to the motor.

Just my two cents.

One of my relays is fried. I wonder if I should replace the relay with a new one, buy new relays of a higher amperage or use a selenoid? How does one make this decision? If I use a higher amp relay am I risking burning up the motor? Is there a way to determine motor max amperage usage? I don't really care if I have wireless remote or not. I guess things will be simplified if I go with a wired switch. Please guide me.

Higher amp relay will not burn up a motor. A relay isn't a protective device just a automatic switch.

I am starting to understand this stuff. Please allow me to ask a few questions to help me understand more.
The relays currently used are 40 amp (same as the motor). I measured my motors amp rating (12v/.3ohms=40amps).

1) Is that the correct way to find amp draw?
2) Does this mean that the motor will only draw 40 amps or does this mean that 40 amps is the normal current draw?
3) Will overworking cause it draw more and more (harmful) amperage until motor burns up?
