Novice Mechanic here. I decided to install Harley streamliner heated grips on my 2014 RK. I used a law-abiding biker video to help walk me thru the process, it was going extremely well. Installed both grips, ran the wire thru the bars, found the right grip pre-wired connection, thought I was home free. I twisted the circuits together by hand first to test that grips worked before using the supplied butt-connectors. Success, grips heated up immediately, here's where the trouble begin, in my rush to disconnect the wiring and run the cable under the seat, the bare ends of the wires touched and sparked (yes I failed to disconnect my battery). I new I was in trouble. I twisted the wires back together and sure enough, no heat. I figured I fried the left hand grip controller and not the harness...and will need new grips, I'm hoping the wiring harness is in good shape. Before you chime in that the in-line fuse in the grip harness should have protected the controller, I had it removed to help me fish it through the fork and handle bars!! (I'll never learned)

Any suggestions in terms of what I should test, i.e. left grip and harness for continuity to start?

On a related topic, in order to get to the prewired right grip lead, and attach it to a fishtape, I had to remove the headlight and the nancelle. I also removed the tank to run the wire thru the channel to the battery.

On the bright side, I enjoyed disassembling the bike and learned alot while having a couple beers and listening to good music

 

Have you checked if there are other fuses in the circuit? What about the fuse box?

 

Like CNCMIKE said, check the fuse box, if you haven't, I'd be surprised if there's not a blown fuse in there. I did something similar while verifying the pin out on a connector and my probe slipped... replaced fuse and was back in business, I was more careful lol

 

Yep, check the P&A fuse..

 

Thanks that was it, you guys are great...big relief! Ready for the winter!
