Review on 💪 Powerful Stinger SGP35 500-AMP Black Relay and Isolator - Efficient Performance Guaranteed! by Joe Greiner

I installed this relay to power an old Warn winch on my vintage 4X4 truck. Firstly, well - this relay can definitely work as a power switch for a winch that can draw a lot of current. This winch traditionally used a toggle switch to physically connect and disconnect the circuit. I installed it and with the flick of a switch I can turn on the winch's electric battery. My main complaint about this relay is that the poles are too close together. The box says it fits 1/0 gauge wire, but I couldn't find any 1/0 tabs that would fit this relay anywhere. I used 1/0 gauge wire for the connections and to connect the copper lugs I had to grind down part of the tabs to get them to sit properly on the relay. On top of the relay, very close to the posts, is a plastic bar that gets in the way. Even the Stinger brand 1/0 mess lugs were too big for the relay configuration. It seems to me that if the relay is intended for high force applications, its contacts should be further apart to accommodate larger wire connectors. Another warning: be careful when tightening connections. There is a lock washer that will break up to a point. If you overtighten it, it will tear off the threaded post. I accidentally ripped one off with very little effort and it looks like it can't be replaced.
