Heated grips

[Simian73]

in the cave doing a few jobs to the 1150, got the tank off and finally doing the fule filter, also got the new o ring and hose clips to refit. While the tank is off I am fitting the optimate lead and a USB charging point near the bars. My left hand heated grip has stopped working so while the tank is off I am checking the wiring. Anybody know what coulours on the connector block are for the LH grip? Presume I just check for continuity and hoping it is a broken or trapped wire? Any help appreciated.

From memory, each grip wiring runs down inside the bars and comes out of a hole near the centre, to terminate in a 2-pin plug with black & brown wires which connects somewhere near the top of that mass of connectors under the front of the tank.

EDIT: you want the very last page, X9351 is the connectors, R9931/R9932 are the heated grips (black & brown wires - memory still working ) and S|9080 is the switch.

The wires are quite fine, so take care. Have fun!

i. My left hand heated grip has stopped working

The L/H side heated grip always breaks, due to pulling on that grip when putting the bike on the centre stand and which over time breaks the element in the grip.

you have to pull on the grip? how quaint, on my old RT11 I just stand on the lug on the stand and use the handle supplied

Same as my 28 year old K100RT.

You star. I'm just ordering the parts to retrofit OEM heated grips (I finally found the right switchgear second hand) and wasn't 100% sure where to route everything as it's not shown on RealOEM.com.

Update....I have tested for continuity on the white plug under the tank and the left bar appears broken, removed grip, I just cut off as I will order some more. Found three breaks in the heating element so will solder aback together and see if that works. I presume a wire of the same diameter (0.25mm) will suffice? The coiled wire on the grips is also two coils not one as I was just going to chop out the complete section but there is a break on both coils.

I've never had to pull on the bar (of my 1100). I just stand on the centre stand foot lug thing and pull upwards using the subframe rail (or for the last five years my Vern pannier frames). Even fully loaded it just rolls back onto its stand.

Don't want to teach granny to suck the proverbial eggs, but you know the grip heaters are resistance wire, don't you...

Thanks again. I've decided to repaint the handlebars while I'm at it so am currently faced with a bike that looks like this:

I had an inkling it was something special but not sure, I was just going to add wire of same diameter?? Not sure if anybody has an old grip they could cut me a section of wire from?

 

[Simian73]

Ok, looked at a few resistance wires for 0.25mm dia, anybody know the resistance per metre? I can measure the grip connector resistance but don't know how long the wire is?

Just bridge the breaks with ordinary copper wire - it won't change the overall resistance of the grip.

There's a Chris Harris video on YouTube showing you how to bridge a break in the wire on a heated grip. I watched it and did my left hand one. Worked a treat.

 

[Simian73]

seen Chris's video (and most of the others, think he puts things across very well) just didnt know what wire he used but if it is just copper wire of similar diameter I will use that. Done another search and found Maplin do a 0.25mm resistance wire with a resistance of 4.2ohms / mtre. I reckon a length of an inch or so shouldnt make a noticable difference so will be getting this tomorrow. Thanks for the advice chaps, sub fee worth its weight !

ok, soldered a couple of short lengths (probably 30mm a piece) in to the LHS grip and checked for continuity...all is good!. Checked resistance compared to the RHS and Left is 8.6ohms and left is 8.4ohms. Turned on and things get warm! refit new grips and all is good.. Just the valve clearances and throttle splitter box to do.
