Brake fuse

[ironwolf94]

I have a 1989 GL1500 and I have just picked up a newer trailer for it. The problem is I connect the trailer to the bile and the tail light is find but when I squeeze the brake to confirm that they work the light come on and the brake fuse blows right away. Ay help would be great, thanks

Obviously something is not hooked up correctly. Did you use an isolator in your hookup? Most trailer companies now recommend a isolaoter wiring hook up that uses current directly from the alternator/battery rather than from the same wire that powers your brake light. My guess is you have too much load on that wire so the fuse should blow.

If an isolator system is installed then there must be a short somewhere in the wire to the brake light. I would start with the connection where the isolator is wired to it.

I would offer some websites to review that sell isolators but I think that is forbidden but you might check with Electrical Connection, and Open Road Outfitters. Try for more info: http://www.openroadoutfitters.com/index ... cts_id=396

Your bike does not have a trailer isolator in it, which is bad - because if there is a short somewhere, you lose all of your brake lights.

I would suggest installing an isolator harness. This is the one I installed:

I would have just built one myself, but this one is literally cheaper to buy than I could build myself. It's been working great for years.
