What are the consequences of wiring an otter switch backwards on an S2? In other words, is a blown fuse the immediate outcome? I’ve been chasing a blown #6 fuse and discovered the otter switch is wired backwards. In other words the black/red wire goes to ground. Using a power probe I’ve confirmed that both the fans work and so do the brake lights.
It doesn’t matter. If it’s an early S2, all it would mean is that the radiator is grounded all the time. That’s not a good idea, but it’s not going to cause any immediate problems. On a very late S2, the switch is isolated, so it doesn’t matter at all.
