I swapped out handlebars last week and ran the wiring internally. Somewhere along the line I must have switched a wire or something, because now my volume control at the grip is all wonky. Pushing it down (-) makes it louder and pushing it up (+) makes it quieter.

Any idea what I screwed up?

I'm asking primarily out of idle curiosity -- I can live with it as-is if fixing it means tearing into the wiring again. Twice was enough for this guy. (That's right: I did it twice. The damned TBW came unplugged on round 1 and I had to redo it all over again one more time.)

 

really I think the only thing you did was put the switch back in upside down. pull the controls off, flip the switch over and put it back together.

 

I don't think that's it. I never took the wiring in the hand controls apart; it was the Deutsch connectors inside the fairing that I opened up. Also, the switch on the grip is oriented correctly -- (+) is on top, (-) is on the bottom.

I'm thinking maybe I switched some wires when I had the Deutch connector apart, but the odds seem pretty long on that -- 12 wires to choose from and I somehow switch only the 2 that control volume? Seems unlikely. (And I don't even know if there ARE separate wires for (+) and (-). That also seems unlikely.)

 

there are in fact separate wires for + and -

and since you didn't pull the controls apart then you just answered your own question.

 

Really? I can't believe I switched two wires that work together. I would have expected to switch volume and horn, for example, so turning up the volume honks the horn and vice versa. Damn, I'm going out to buy a lottery ticket!

And I'm living with the volume control as-is.
