The heated bar grips on my R1150R (2004) have stopped working. Please read the following tests I have performed before responding. Thank you for any helpful advice i.e. solutions or further steps to diagnose the problem.

• The Load Relief Relay works, because all the other components that use it work i.e. Lights, Horn, Turn signals
• I have also tested using an alternative Load Relief Relay and the heated bar grips still did not work
• There is continuity between the Load Relief Relay and fuse 7
• Fuse 7 has continuity i.e. its not blown
• There is continuity between the fuse an the input to the switch
• There is continuity between the input to the switch and the output of the switch, which indicates that the switch works
• When I turn the engine on and then turn the switch on I do not get a voltage reading at the switch input. I set my multi meter to both 50 volts and 10 volts but still got no reading. The – (negative) end of the multi meter was connected to the – (negative) terminal of the battery.

What was measured resistance across each heated grip? Easiest access to the heated grip wiring is under the fuel tank, at connectors.

I attempted to measure the voltage at the input (Green/Black) wire on right handle bar switch, after disassembling the switch gear.

I have now discovered that I do not have continuity between the fuse and the right handle bar switch on the Green/Black wire. Previously I achieved a false reading because I was testing the switch when it was turned on, hence leading to the – (negative) battery terminal. When I turn the switch off I do not have continuity on the input to the switch.

I need to trace the (Green/Black) wire from the fuse to the switch. Where are the connecters? Under the tank?

All connectors are under tank, both hand control switches and the grips. Connectors are fastened neatly to front subframe.

You can troubleshoot both switchgear and related components like heated grips with your multimeter and appropriate probes. Some of the OE connectors require creative approach to gain access to contacts.

Not sure the load relief has any bearing on heated grips operation. More likely a broken grip wire or wires.

Haven't read of anyone experiencing difficulties with the grip switch itself.

Do you stll have the nylon ties holding the wire bundles under the steering head? If so, there is probably a broken wire under the sheath as that has been a common problem with the overtightened nylon ties and the right/left movement of the steering head.
