Run/Turn/Brake Controller
Ran into something that puzzled even an experienced electrical guy so I thought I would share:
When I put my J&M amp in a couple of months ago, all was perfect. About 2 weeks ago, as soon as I would turn the switch to ignition or accessory and the amp kicked in, i started experiencing an electrical "buzz" also known as a ground loop. I didn't pay too much attention to it because once the bike was started, it could not be heard anyway but was quite annoying when the bike wasn't running.
Fast forward to last night:
I was troubleshooting a brake light issue (turned out to be the brake light relay in the fuse block failed but did not throw a code as it's supposed to do) and I just happened to pull the run/turn/brake light controller off to test wiring at that point. Low and behold my buzzing stopped. I'm like what the hell? How would a brake light controller in a brake light circuit have anything to to do with inducing so much noise into my electrical circuit especailly a circuit that is somewhat isolated? So I crack open (trusty ole dremel tool) this sealed case and find a slew of diodes in it, one of which had a crack in it. The controller itself was still completely functional but that diode apparently prevents voltage (-voltage) from feeding back into the rest of the electrical system. Tested all my brake lights and others for the tour pak and rear light bar all was working fine except for the 2 turn signals functioning as brake lights as well. At this point and $50 for another controller I just said the hell with it and left it without the controller.
Crazy stuff!
