Title: Electrical, power for the heated handgrips
Post by: Qdude on February 11, 2013, 11:27:50 PM

I discovered that all three of those center handlebar switches were semi-connected.
I cranked up the soldering iron and had some fun.
I now have hazard lights!

The ABS switches wires were completely M.I.A.   ?

The heated grips center pole (purple?) had been 12 V when the key was on and O V when the key was off. Perfect. So I proceeded to repair the switch.

When I went to test them afterward, there was no longer any power at that center acc power wire that had been working not 20 minutes prior.

I tested all of the fuses on the left side of the fuse box on the left side of the bike. All good.

I tried to trace the wire as it went under the tank... Not so good... Got lost...

Where would you all point me to look for this source?
Would you suggest pulling the gas tank?
Would you suggest pulling the fairing?

I don't have a problem doing this, in that I would really like to get all of these electrical problems handled. I would not mind doing it right...

The tank is full. Is there a thread that describes the best way to get it off?
I know they are made of aluminium and can get damaged more easily than the steel or plastic tanks.

Tanks everyone...

Removing the gas tank (http://www.motobrick.com/index.php?topic=535.0)         

The factory wiring harness for K bikes has a connector for heated grips.  It is a "T" connector which has short leads and can be found under the tank on the left side about two thirds of the way back.  It has two wires.  The green/black wire is switched power from Fuse 1.  The brown wire is a ground.

The center wire on the HG switch should be green/black.

I'd recommend not using the low setting for extended periods of time (or at all.)  The low circuit has resistive wire under the tank.  If you leave the HGs on the low setting long enough that wire has been known to heat up, melt it's insulation and cause shorts and smoke under the tank.  I had this happen on my 93 LT. :yow

If you want to disable the low setting to make sure this never happens then cut the orange wire on the back of the switch.
