Would someone help me to understand how I can convert a 120v AC winch from harbor freight to a remote control winch using mostly off the shelf circuitry.
The AC winch uses a bridge rectifier to convert to DC and that goes through a wired control before making it to the motor.
I’d like to use a 120 v rated receiver that is available off of Amazon to replace the wired control. The 120 powered receiver has a reverse, common, and forward connection but since it is being fed by AC the voltage comes out AC so the necessary polarity is not present to make motor work in reverse and forward direction
I’ve thought about two different solutions.
1. use a bridge rectifier convert to dc before entering the receiver, but I’m afraid that the 120v DC will damage the 120v AC receive
2. Use a normally open relay switch on the common leg of each common wire going to the motor. Can I set it up to have the each side close it’s own relay to complete the circuit to a bridge rectifier before going to the motor. What should I watch out for using this method?
