Repairing my Harbor Freight ATV Winch

Just what I needed to repair the Harbor Freight "Badlands" ATV winch. This pair of relays was a direct replacement for the relay in the winch junction box. Just take the old relays out and put the new ones in. Make sure to correctly assemble the connectors of the smaller coils; Maybe take a picture before you swap the relays so they are in the right place. One final tip: each replacement relay has a plastic mounting tab that can make it difficult to fit into a small junction box. You can just cut off the plastic tabs. These are pretty cool relays for a variety of purposes. Each has two small male pins for 12V DC coil and three large male pins for COM, NC, NO. With a contact load of 80A you can switch quite large loads. I suspect the 80A rating is for resistive loads like lighting. If you are switching an inductive load you can reduce this rating slightly or use a flyback diode to shunt the load to suppress the high voltage spike when the contacts open.
