Problem with heated grip on F800GS

[Lord Snooty]

My right hand heated grip has stopped working. I have removed the rubber grip and with the grip on full heat I am getting a constant reading of 13.5v across the soldered connections to the element. This would indicate that the element does not have a break in it otherwise there would be no reading.

Might this be a software or Canbus problem? If so is it possible to perform some sort of reset?

Any ideas please?

I'm not sure your conclusion is right. If the element is being fed 12v, and the other end is earthed, you will get a 12v (or 13.5) reading across the terminals whether the element is good or bad. What you won't have is any current flow.

Disconnect the wires and do a continuity check. It should be very low - a few ohms I suspect, but anything other than open should be a good sign.

Alternatively, just disconnect the low side / negative lead and then check the voltage from that to the battery negative with the heater turned on. If the element is good you'll see battery voltage, if there's a break you'll get nothing.

BMW diags confirm the grip has failed so I have ordered a second hand one from Motoworks - half the price of a new one.

both grips on mine don't seem to get as warm as they did when i first got the bike,could this be a sign that they are about to fail ?

No idea Carl but it might be worth taking it to a BM dealer to plug into the diags machine in case it is a software/firmware or canbus problem.

Nope - have you recently bought thicker gloves ?

CrazyCaz's left hand one broke, just didn't heat up. New grip sorted it.

If there's some heat in them, they're not broken. A lot of things affect the heat level, such as the position of the hand guards. Try checking such things first.

Mine where like that it was the switch on mine,
It was only working on the first setting worth checking it out

An old thread I know but mine have stopped working on 08 f800, after I replaced the rubber grips. I was so careful removing the old grips and am wondering how to check if I have broken/slitted a wire. I have a multimeter but have no idea where to point it! Lol
