Had a problem with my '99 SX 600 where the hand warmers worked intermitantly. I did a site search and found several things to look over and test. The problem ended up being the wiring harness in the steering housing. I took the sled out and they do work but, I am questioning the voltages that I got when I tested them. At idle (1,600 rpm) with the temp controll turned all the way down I get about 5.7 VDC and about 3.1 VDC with the temp control turned all the way up. This doesn't seem right to me. I had one meter lead on the 10mm bolt that grounds the system and the other lead touching the yellow/red wire. I did the same test with each of the black wires and got the same results. What should the voltages be for this sled?

You might be looking at it the wrong way.
Try the resistance from the harness thru the warmers instead. The voltage is variable but the resistance of the warmer should be constant.

The resistance is variable.
The temp controller is a rhiostat.

Might be of some help.
What I was referring to was the grips should be a steady resistance. The voltage going to the rheostat is the only voltage you should be concerned with.

Ok - if the temp controller is a reiostat then the voltages I am getting are correct because at a low temp (i.e. low resistivity) I should get more voltage and at a higher temp (i.e. high resitivity) I should get a lower voltage which is what I am getting.
Next question - what should the peak voltages be at 4,000 rpm? I would link around 12-13 volts at the low temp setting and maybe around 5-6 volts at the high temp setting. I did my initial testing at idle around 1,600 rpm and I am seeing in the posts that I did the search for that the voltage changes through the rpm range until about 4,000 rpm.

When they work intermittently is it the hand warmers and thumb warmer all at once?
I'd check the grip resistances.
In the PDF I linked to it mentions that you will see 20.3VDC off and 22.6VDC on. I don't know what that means on your sled though. Also I thought the grip circuit even on a "battery equipped" sled run on AC. Set your meter to AC scale and try again.
Whenever we had grip heat issues in the past it has always been a grip going bad. But those were either 2 heat setting or on/off type circuits. I'd also make sure the rheostat is working right. And if your key switch is like mine with 2 on positions one for grips and without grips maybe there is something loose there.

Hey guys' since your talking heated grips here, question?I cannot turn my temp. setting over half, if it goes over the half way the thumb warmer gets so hot it burns your thumb! It actually burnt the throttle lever! Got an answer for this one?It's a '99 venture.

Nope. My '97 Vmax seems to want to set fire to my thumb as well. I imagine you might be able to put a resistor inline with the thumb warmer to drop it's temp a bit but what kind of and what value of resistor I cannot say.
The thumb warmer on my 97' SX700 is one hot mama.
I cut off the right thumb of an old fleese glove and wear that inside my glove and it keeps the thumb warmer from burnin.

Well thanks again guys' I guess its another quirk in the system! Maybe it's a good thing, a guy can put a slice of bread inbetween your thumb and throttle and have toast!!!
