QWORK Solenoid Relay, 12V 500A Winch Relay Solenoid Replacement Contactor for 8000-15000lb ATV UT Winch Control

Easy to wire up and worked well with no issues. Has the same flipity flopity as another review. Hopefully it last a while. If not, it was cheap enough not to worry really.

Yes, this was an exact match for the Badlands winch from HarborFreight

This reversing relay has small studs with 10 mm nuts- 6 mm studs I believe. The two internal relays are operated by the each one of the outer spade terminals being either energized or grounded to the center terminal. The solenoid terminals do not appear to require a certain polarity so either positive or negative control is possible. The default seems to be ground control since a pigtail between the center pin to the positive battery stud is included. A wiring diagram is not included but the arrangement of power supply was good for my situation: The positive and negative terminals are alternated to the two motor terminals by energizing one solenoid at a time. If both solenoids are energized simultaneously, the unit will not short out. This is meant for a two wire reversing motor where battery power and ground are only provided to motor through this relay, not three wire motors where the ground is provided directly from motor to battery.

Works great

Very heavy duty relay/contactor switch. Works great and was really easy to install.

It does not carry the current started. I punched 4 and tested two on a small DC motor. Tilt/trim for a boat. It got hot, the switch and tilt motor.

Works fine.
