Factory Heated Grips stopped working

[mfletch69]

I was in the N. GA mountains last weekend and turned the heated grips on.....nothing happened. Read the manual and it only says how to operate them. Does not reference a fuse for the heater at all. I pulled the panel by the battery and all the fuses look fine.

Anyone know where it is?

Thanks in advance.

If you have the most common set up you'll find the power for the grips is taken off the hot wire that goes up to the brake light switch on the front brake lever. The fuse is in one of those cheapo in line plastic fuse holders somewhere in the wiring in front of the handlebars. you'll find it by tracing the wire from the brake switch.

I just repaired mine this weekend, it wasn't the fuse but rather a bad connection in the wiring between the power take off at the brake switch and the fuse holder.

Ol' mfletch69 has one of them there newfangled AE thingies with built in heated grips.

The grips are powered by the Signaling System Fuse. If the horn works, glove box opens and the rear brake light comes on when the front brake lever is pulled in, the fuse is good.

Check to see that the Black and Gray two wire connectors are plugged in. CONNECTOR LOCATION, thanks V65! If they are plugged in, unplug them and ohm between the two black wires in each connector -- it should read nearly a short (~2-3 ohms) on both the Black and Gray connectors. This test is verifying the grip heaters are good. If one or both are open (has high resistance) you have an broken wire to the grips or a broken wire within the grips.

If these checks don't reveal the problem let us know and we will guess diagnose further.

There is a high probability that if the fuse is good the throttle grip heater element is open.

I also recall that the OEM heated grips power from the infamous "blue connector" which is a secondary load off the headlight circuit.

However, I could be wrong. I've slept since then.

There are two connectors associated with the Heat Controller. One connector is indeed Mr. Ashe's Blue connector which contains the R/B power control wire going to the Black grip connector, and a G/L (green/blue) wire that senses the headlight circuit relay on/off state. The second connector has a B ground wire, and a G/W ECU control wire.

The horn, glove box and brake lights are working. I will do the OHMS check. Hard to believe BOTH grips would have a wire failure though.

Thanks for all the help though!

Step one, we know the fuse is good!

The grips are in series, if anything goes wrong with either grip both grips quit working. In fact, almost all the wiring is in series from the +12 volt power going to the throttle grip, through the connecting wire that joins the grips together, to the wire from the clutch side grip that goes to the power controller. If any part of this series connection fails everything goes cold.

You know I'm partially colorblind. Glad you have all the colors down pat.

You can also check inside the throttle housing assembly for problems. The heater wire inside mine got bound up in here and ended up rubbing the wire in half. Required some soldering and heat shrink to reconnect.

And the winner is....ADANIEL! Wire in the throttle assemble was broken. My bet is that installing the G2 began the problem. Soldered/heat shrinked and HOT as hell again.

Thanks all.

Glad to see you got it fixed. I'm not a big fan of the twisted loop inside the housing. I added a little extra lubricant inside the housing to try and keep it from dragging.

G2 here as well...unfortunately I got the G2 for the A model (shorter) and then ended up getting the heated grips. Too stupid to get rid of the A/std G2 to get the AE G2 which is a little longer.

I now know to stop and check if the throttle repsonse gets a little tight and slow to return.

Came across this thread after googling heated grips site:fjrforum. Went riding today, was cool this morning so I turned on my heated grips ('06 AE) and only the left one heated. The right one did not heat up. Will check inside the throttle housing tomorrow (installed g2 18 months ago, no problems last winter).

From reading this thread, seems usually grips will completely go out if they &/or wiring screws up. Any ideas? Horns, lights, glovebox, etc work.

Last but not least, bike was wrecked returning from Arkansas vacation 28 June 2009, we were pulling luggage trailer, couple in their seventies didn't see us and broad sided our trailer (barely missed hitting us directly). Trailer tried to flip, causing bike to slap down on right side fracturing my wifes right foot, then trailer tried to flip the opposite direction causing bike to then stand up and slap down on left side. I walked away with lower back pains but have recouped fine, wife's bones have mended, but she wears a size 8 shoe on left foot and a size 9 on right foot, yeb, over three months later and her foot still gives her problems. Complete exhaust, both side bags, dauntless hitch, skyway sliders (with highway pegs), large right fairing, and foot brake peddle had to be replaced. Strapped bike on a uhaul trailer to get it home (rented 10 foot box truck as well, luggage trailer went in box), didn't have any other way to secure the front end other than going around the grips with ratchet straps, towed it this way for 500 miles. Could this have caused it?

Wow. Nasty accident. Could have been worse, you could have been riding your FJR instead of trailering it. Ouch.

The grips are wired in series, so there's something like the wires to the non-working one shorted together. If that's the case, I would expect the working one to get hotter than usual.

Look for the wires with soft rubbery insulation round them. Could be both wires to the grip crushed together, or could be a short to ground. It could be anywhere along the loom, not necessarily within the throttle grip housing.

This is where my problem is as well. Removed the housing, both wires were chaffed and melted together just as it enters the actual heater element. Not sure if I can repair it because the wires are broken were they enter the element as well, so not even a pigtail length of wire to try and solder to.

Bike is under YES warranty, so I'll give the warranty a try.
