Ain't it typical winter has arrived it's minus 2 degrees out there and now my heated grips have decided to pack up today I've a k6 Ive not had chance to have a look at anything yet as its dark at half three but hopefully I will get chance at the weekend does anyone have a wiring diagram or any hints ......please

Are they Suzuki heated grips? If so, they are wired in series. A bad connection or controller/switch will knock out both grips. So will a break in the wire inside a grip. One wire from each grip connect together. The remaining free ones are connected to earth and the controller.

Other brands usually are connected in parallel. If both are out, the controller/switch or the connection to power are the likely culprits. A problem in one grip or its wiring will not affect the other grip.

A recent posting spoke to loose connectors causing failures. I had a weak left side, just unplug, re-plug the connectors made it better.
