I was just going to start the project but I want to make sure I am doing it the correct way....Where are you getting your power from to feed the reostat? And if you do this, can you still shut off all the warmers including the thumb warmer with the key? Also, run the thumb warmer without the handwarmer? Let me know....Thanks a bunch!!!!!! I have a wiring diagram and a manual:)
PS I did a search and I could not confirm and concrete info!

heres what i tried....cut the wire to thumbwarmer spliced an another rheostat....didnt work too well burnt out the rheostat...then tried taking power from handlebars through rheostat...didnt work too well burnt out the rheostat....i am looking for a way to do this.....if you take a 2 ohm or 4 ohm resistor and splice this inline it should drop the power a couple volts...kinda stupid burning your thumb while your hands are cold....heard of a guy on here buying a aftermarket thumbwarmer kit and using the switch with it to set full power or power through the resistor in the kit...maybe somebody else will chime in
 
Ya I hope so, because I am all setup to do it and then I read one of your posts that I found in a search and I don't feel like burning up all those reostats:).....Let me know if you figure something out....Thanks RR
 
well the way the warmer system works is the rheostat controls the voltage regulator...so any way you turn the rheostat controls the power output...the only way i can think it to use a resitor inline of the thumbwarmer...you can probably find these at radio shack, the source or any electronics store...might work...i know this has been done before just to figure out how
 
I should be able to test what the voltage is in my system know and then we will be able to know what size resistor I am going to need.......But wiring in restistors and chit is a lot more work then I wanted to do :o| :babe: :beer:
 
wiring in a resistor is fairly simple they come with a lead on each end of the ceramic center....cut the wire then solder to each end of resistor and heat shrink....or try this....one guy on here took a 25 ohm rheostat so im gonna try and find one of those....
heres the link hope it helps....
if you need any help wiring let me know....

TY member 2Stroken worked some voodoo on the sled I bought from him regarding the grips and the thumb warmer. The way I under stand how he did it is that the grips control is the "master" and the thumb control is secondary. Basically I could never have more heat in the thumb than in the grips. Not sure how he set it up but it's a little variable knob next to the warmer knob.
 
Can someone look up the full wiring diagram off of a SRX with serperated thumb and hand warms. Perferable a one out of a manual for a 02....I have a manual for a 98-99 and 00-01 but I really would like the 02 wiring diagram.....this way I can cross reference what I am trying to accomplish.

That would appear to be the best way to set it up. Just wire the second VR into the power feed wire of the thumb warmer wires. It shouldn't be inline but mounted outside the harness so it can dissipate the heat without melting the harness. Then it would also be variable in regards to the amount of heat produced at the thumb warmer. I might do this to my 600 as the thumb warner actually get too hot.
 
In order to accomplish this......I think that i am going to need to get another voltage regulator to tie another variable resistor to so I don't fry them like chevy did. Then I should be able to pull power off of the y/r wire and then put the voltage regulars and variable resistors in line with the grips/thumb warmer. That way there would be two separate circuits one for the grips and one for the thumb and each would be able to have separate voltage drops across the variable resistors make them work individually. But it involves changing all the wiring for the grips and I am not sure that I am going to go through all of this trouble...... :o|I am sick of having to hot of a thumb but I could also just make is so I can unplug them ;):D
 
well i think i got it figured out....tried tieing into the hand rheostat...there is no power going to this so it wont work as a feed....so i took power off the headlight switch on the handlebars...then ran it to a 25ohm rheostat and tapped that into the thumbwarmer....workin so far...

seems like alot of work, but couldn't you just use a wiring harness from a 01 or 02 srx or viper?
 
Nope the 01-02 srx I know is split in the cdi box....it is wired completely different!! It is a lot of work if you want it to be just like stock, where the key turns the power on to the warmers and then you can use each one individually with out having to have the other one on. I can get it to work by taping into another power source like chevy did, but then they are on all the time, granted you can turn them down all the way! Just havent figured out what to do completely.... :dunno:
 
This is for a machine with factory hand and thumb warmers but only one dial to operate both.
You’ll need an aftermarket thumb warmer kit for this project.
At the handle bars, remove pad and foam. Locate black and white wire coming from thumb warmer. Between thumb warmer and factory plug cut the white wire. Attach white wire coming from factory plug to the middle blade of the three-way switch (Hi-Off-Low) supplied with the kit. Also from the kit connect the supplied “Y” wire with the included resistor to the switch. Wire from the resistor goes to the top blade of the switch; remaining wire connects to the bottom blade. End of the “Y” wire gets attached to the previously cut white wire coming from the stock thumb warmer.
After mounting the new switch and making sure nothing will short, you will be able to turn off the thumb warmer by selecting off on the switch. Hi will work just like stock, hot thumb warm hands. Putting the switch on low, your hands will be warmer than you thumb.

Hope this helps - Derek

I used a variable resistor, I can't remember the wattage or anything, but basically I got one that was I think equal resistance to the thumb warmer. I think just put it in series with the thumbwarmer. I think that is what Dnale mean by inline. I was always burning my thumb before, if you wanted to do some testing, you could go to radio shack and get some hiwattage resistors, and change them while inserting them in line until you get the desired heat reduction. I think the SRX has a 300W magneto, I assumed that about 15V would be what I would see out of the system.
Measure the resistance of the thumb warmer

(V^2)/R= P

V/R=I. So just make sure you get a pot that will handle the wattage.


What Dnrtheil did will work also. That is basically what I did, except get rid of the switch and just use the pot where the resistor is.
