Heated Handgrip Failure (left side)

[ebincia]

Today I noticed that my left side heated (clutch side) handgrip has stopped heating up. I have checked for pinched wires where the way too tight zip ties used to be. The wire for the left handgrip seems intact. Before I can research any further I will need to remove the tank or take apart the handlebar switch mechanism. Before I do either I wanted to ask here if anyone has experienced this problem before.

Thanks in advance for your response.

Left side heated grip failure seems rare; it's usually the throttle-side that fails due to twisting inside the handlebar.

Simplest diagnosis of a heated grip wiring fault would be continuity check at the connector located under the tank.

Good luck.

As sweatmark said, in 99% of all cases it is a wire failure. Check the connectors and measure the wires from the connectors to your grip. Locate the failure and repair. Enjoy riding again. If it is this rare 1% where the failure occured under the grip you're in trouble. You will then have to get yourself a new (or used) grip unit to replace the faulty one ...

I had a left hand side failure.
I first assumed it was the dreaded wiring around the headstock, but took the tank off and traced it back, to find it was the actual grip itself. I removed the rubber grip and located a tiny break in the heating wires. I was able to repair with solder (after much swearing) - had to make a small cavity for the solder and paint on some flux.

Please help!!!!!!! I've verified continuity in the grip circuit at the connection point underneath the tank and at the point where the wires enter the grip. The left circuit has continuity similar to the right. Also verified that power is getting to the left side in same measure as the right. However, the left still does not hear up.

Thanks in advance for your responses.

Well if you have checked the wires are OK at the connector under the tank as well as at the grip the only option is that the heat-wires under your grip are damaged. Maybe somebody has changed the rubber grip and damaged the heatwire? In any case this cannot be repaired and I suggest you get yourself a new heated grip or try to find a used one ...

My left heated grip stopped working a couple of years ago. When my left hand gets cold I just cross my arms and use my right hand for the clutch and left for the throttle. When my left hand warms up I swap back again.

1. Checked the corresponding fuse? Circuit continuity could signify a short just as easily as good wiring. What's the resistance of left versus right side heated grips as measured at the connectors?

2. Assuming that fuse is OK and you're getting right-side grip heating but not left-side, and that continuity checked out OK for the left-side circuit, then my only guess is a wiring fault within the harness (between connector and grip) that separates occasionally and prevents current flow. If wiring fault caused short, then fuse would blow. If resistance heating wire within grip was broken, then circuit continuity would not check out.

3. Grip heater switch cannot be issue if one grip is heating as designed: the switch handles single power wire that splits near front subframe connector.

I think that's far too dangerous Hank, If you would just turn around in the saddle you could avoid crossing your arms and a possible loss of control.

Too true, crossing your arms while riding isn't safe. What I do now is, lay across the tank with my hands in my pockets so that my wife can lean forward and take the controls. This allows us to continue our journey while I have my afternoon nap and warm my hands at the same time. I also find that draping a towel over the tank stops my drool from spoiling the paint work.
