Installing adjustable Hand warmer on Phazer

[dmaxx]

Anyone try to use an adjustable resistor from a sx700 on a 99 Phazer that has no adjustment. I have one I would like to install on my daughters Phazer so she wont burn her thumb! Just curious where one might splice which wires and where.

 

[MrSled]

u can splice into the blue wire under the pad or run it off the same feed as the hand warmers...

 

[dmaxx]

Thanks Mr. Sled. Do you ground one wire or slice both?

 

[MrSled]

use the same hand warmer ground as stock or one of the black wires...but check it to be sure

you should really wire it like a 500. the hot grip power feed runs directly into a seperate regulator and the variable control is wired into that same regulator. Kinda easy to do just need to add the reg and one extra wire other than what you have....

 

[MrSled]

but the stock hot grips on the older sleds are regulated....right...hmm, maybe I am wrong....

I have a regulator from a Bravo would this work and how do I wire it? I have a schematic for 500/600/700. The hot wire to the grips and thumb warmer are yellow/red.

 

[MrSled]

I would wire it without...you have a voltage regulator on that sled or your headlights would pop.

Can anybody confirm they successfully installed a Yamaha variable resistor (rheostat) on any sled with only an on/off switch? I'm thinking I could just splice one inline between the switch and the hand/thumb warmers, but Yamaha wiring diagrams show the rheostat connected directly to a voltage regulator. I can't tell if the rheostat would work independently of that particular regulator. I want to add one to a 2001 Polaris Indy (Lite) 340.

A rheostat (variable resistor) adds more resistance as you turn the dial and therefore decreasing the output. If the factory thumb warmer uses the same feed as the handwarmers and is run thru a resistor (like the aftermarket Hot Grips) and you want to simply regulate the thumb and not the handgrips with a reostat I would say you want to connect into the circuit before the stock resistor and feed the reostat? Who knows if this would overload the Phazers grip warmer coil and voltage regulator? You would have to use good old OHM's LAW. First, determine the output capibilites of the gripwarmer circuit and subtract the handwarmers current (amp) draw then see if there is enough amperage left to run the draw from a rheostat and thumb warmer resistance.

(PIE) P=Watts I=Amps E=Volts
_Watts divided into 12 Volts =_ Amps
_Watts divided into _ Amps =_ Volts
_Amps x 12 Volts = _ Watts

(VIR) V=Volts I=Amps R=Resistance (ohms)
12V divided into _R = Amps
12V divided into _A = Resistance
_Amps x _ Resistance = Volts

n. 1. (Elec.) A contrivance for adjusting or regulating the strength of electrical currents, operating usually by the intercalation of resistance which can be varied at will.

So has anyone successfully pulled this off? I'm about to attempt to do the same thing to a 99 phazer, using a rheostat from a 98 mountain max. The phazer only has "on/off" setting for both grips and thumb warmer and runs way too HOT! The resistor comes with a plug on it but I doubt it will be as simple as just plugging it into the phazer. Just wondering if anyone's been able to do this correctly and with no problems and if so how'd you go about doing it? Any help appreciated, thanks!
