Have an old DSS300 that someone ran something into one of the openings of the cover and destroyed the lift heatsink transistor. I replaced it with what I thought was a good used part(since boss is cheap) at the time onto the truck and repaired the wires that damaged. As soon as lift function was used it blew that one as well. I checked the lift motor and it ohms out fine along with the wires going to it. Am I missing something? Can a regen cause it?
