Heated Grips

[Greggers]

Yaaas

I also have Muffs - but they aren't always fitted .... and yes, I know they should have been on last week too ...

Still doesn't address the reason for failure though.

I had some Oxford grips on my old RT (have I said already?) but on max they were too hot !

I know it sounds soft, but on those chilly days the heated grips just make it a little 'easier', but one on and one off is a fookin nightmare!

Similar problem

Hey Greggers,

Did you get your heated grips fixed, mine has just developed similar problem, RH stopped working mid-ride this afternoon. I've open up behind the switch & had a look a the wiring couldn't see any break, sprayed it with WD40, worked. Screwed it back together - stopped working again

Looking for insight

 

[Kaze]

Have had another look and on closer inspection discovered a broken wire, top view and then rider's eye view:

Now I need to figure out how to split the plastic bits so I can attempt to fix the wire, any tips people?

 

[Greggers]

Interesting about the broken cable - I;ll look at mine too. If you're handy with a soldering iron it should be a simple fix ...

Here's the tech juice for the grip ...

Thanks Greggers that's really helpful.

Progressing well but am struggling with disengaging the throttle cable. Will ask the question as a seperate thread. Will keep this thread posted on progress.

Fixed it ...

I fookin fixed it!!

The heating element is a printed film job, a flexible printed circuit if you like...

I took Kaze's problem on board and whipped off the throttle grip - Kaze, did you manage to get yours off? - and isolated the cables feeding the heater. The cables (the one that Kaze had that is broken) were fine, but there was no continuity at the terminals - bugger! I tried to unpeel the grip, but lost patience and cut the assheule off. I found one section of the circuit track that had burned through - no idea why - but thankfully it was close to the edge of the grip so I was able to bridge the break with a small blob of solder without shortening the track too much (which would have upset the canbus).

Putting another grip on was a struggle as the throttle tube has all sorts of ridges and bumps on it, none of which help to slide a grip on at all...

Tomorrow I shall be mostly trying to re-assemble everything ... lol

If you want pics just shout and I'll post some...

@ Kaze - getting the throttle tube off is quite simple - did you manage it ?

[Kaze]

Thanks Greggers

Yes thanks, was being far too gentle or fear of damaging the cable, Jokers tip paid off.

Fixing the break's going to awkward now, couldn't have snapped at a worse position

 

[Greggers]

Arse ...

Yes, I can see what you mean!

That rubber moulding fits in the cut-out on the throttle tube and acts as a grommet/spacer to prevent the wire chafing - as you've discovered, it's moulded onto the cable so can't be removed ...

I'd be inclined to solder a short section of wire - make sure it's multi-strand and quite flexible - to by-pass the spacer, but leave the other cable in situ. I don't think at the moment you've anything to lose by trying to fix it... So, this is what I'd do ...

Make a small pependicular cut in the bottom or the side of the rubber spacer - making sure not to cut the other cable in there - so that you can snug the replacement section into it when you push it back into the locating channel on the throttle tube... that way it will still locate the wire firmly and will keep it out of harms way and still let the other wires rotate freely inside the channel on the switch side of the tube ...

best of luck!

Here's my repair to the circuit film...

Here's the point at which the 'element' burnt through - I still don't know what caused it, but a hotspot's a hotspot! To give you an idea of scale, the length of the zig-zaggy bit is probably 10mm or so, but ... looking at the pics in more detail shows other hot-spots on the adjacent tracks too - I can expect these to give problems next... if I'd seen these last night I'd have bridged them too. Ah well, next time!

If you follow the circuit track you can see that the point I've chosen to bridge the break doesn't lose too much length. The repair point will be just to the left of the break - I scraped the film off until I got to the copper track underneath ...

a little electronic solder later and here's the result...

.......................

I had to sacrifice the grip to get at the element, but getting the replacement grip back on was a complete arse, especially as it was about 10mm too short ... I wasn't in the mood to struggle any more, so I used a little self amalgamating tape on the end of the grip to seal everything up ...

Next job will be to fit matching grips - if in all honesty I can be arsed!

Another fix!!

Appreciate all the help & tips along the way! Particularly The Joker & Greggers - thanks folks!!

Was expecting it to be a right pain, but in the end only took about 30-40 min's:

1. Sliced the plastic shroud down the length adjacent to the snapped wire, pulled the wire out and soldered in a new length;
2. Sealed the joins with a piece of shrink wrap;
3. Cut away a small corner of the plastic shroud to allow space for the thicker wire, particularly at the join;
4. Squirt of silicon lube on the wires, particularly over the shrink wrap where the wire was soldered (should help stop any potential snagging);
5. Refitted the handgrip and put it all back together... and ...
6. Success! Hot hands again!

Call's for a small celebration eh

Heated grips not working

I have an 08 F800GS with heated grips. They have always been generally weak. I know this because when i borrow other F800GS bikes, the heat is a lot better than mine.


Now one of the grips has stopped working altogether.

What is the most likely cause?
What should I be testing when i investigate?
Assuming it's the grips themsleves, are they difficult to replace?

 

[argee]

Hmmm, I suspect they're broken.


I'm not an expert tho.....


An expert will be along shortly, don't worry

 

[Aran]

Sounds like it has gone "phut!"

It'll be broken now.

Well, if I've posted it properly.

Good luck!

I was just about to say the same thing

Heated grips failure! Again!!

I've recently replaced my battery, the old one died and wouldn't keep charge.

Everything works fine except the heated grips which don't work at all I've checked the wiring and can't see any signs of physical damage. Any idea's people?

 

[Greggers]

Holaaa...

So, both grips have stopped at the same time? I'd say that it's prolly a CanBus thing, but I'm equally surprised that it's not just reset itself. Do you need to get the dealer to reset the service indicator after disconnecting the battery? If you do, maybe ask them to interrogate your ZFE unit to see why it's not working and see if they can 'switch' it back on again.

I had an issue with one grip failing due to a broken track in the heating circuit, but that was under the grip itself so wasn't immediately obvious as a wiring failure...

Kaze get yourself over to see Jonno at http://www.adventurebikewarehouse.co.uk/

He has a GS911 tool which can do Canbus diagnostics. I think they give out a code for any problems & also fault find. Just a thought,..it might be worth giving them a call.

Thanks Folks, had it diagnosed by the dealer yesterday, both grips have failed, will have to see if they're repairable otherwise it's 2 new ones
