intermittent heat on HD grips

Hi all, the factory heated handgrips on my 2006 RG work inconsistently, and now that the weather is cooling off, this is kind of frustrating. I've been searching here for clues but haven't found much. With the controller turned up to 6, either both grips work fine or both are dead...must be a weak connection somewhere. Are there known areas of weakness with these things, like pinch points or bad connectors? Also, I've been looking for the fuse, can't find it anywhere...I read somewhere it's the P&A IGN 2Amp fuse in the fusebox, but there's no fuse there in my bike. Any thoughts or recommendations appreciated. Peter.

When you say factory, are you saying that the heated grips came installed from the factory? Or are they OEM grips that someone installed?

That can make a difference on where they were wired and got power from. If they are from the factory the wiring diagram in your service manual should show where they are wired. If a tech or individual wired them, they could have tapped into another circuit like I did on my bike. I tapped into the circuit feeding the 12V accessory plug that I will never use.

I haven't torn apart a set of grips to determine if the controller is a simple rheostat or if you have to have it perfectly aligned with each number for there to be power. If it is the latter, then simply playing with the position would solve your intermittent problem. If the former, then you will have to trace the entire circuit looking for you problem. I am leaning more towards the grip controller myself. The fuse is either blown or it isn't. There should only be the connector that connects the left side to the right side and the connector that connects to power.

Good luck.

Does your controller look like these? Harley Davidson 56100034 Heated Hand Grips - Black Rubber

They say they are for '08 and newer so not sure what they changed.

I should clarify they are "HD" brand grips, but since I bought the bike used, I'm not sure who installed them. (The PO got the dealer to service and modify the bike, so I suspect it was done by the dealer.) They are chrome with black rubber strips (tried to insert photo, not yet allowed). Intermittent positions on the controller don't do anything - the heat is either all there or nothing at all. I guess I'll try to trace the wires and see what I can find. Thanks for the suggestions and advice! Peter
