Hand Warmer Diagnostics

There are two types of hand warmer element pads used 
on Polaris snowmobiles.  One version is used on steel/
painted handlebars and touring model rear passenger 
grab bars, while the other is used on aluminum (Pro 
Taper) handlebars.  The difference between the two hand 
warmer element pads is in the resistance values.  A lower 
resistance element pad is used on aluminum bars 
because aluminum dissipates heat faster than steel.

A common misconception with Polaris hand warmer 
elements is the higher resistance circuit is the high 
temperature element.  In reality, the hand warmer circuit 
with the least amount of resistance will flow more current, 
and thus create more heat.  This is an important fact that 
must be taken into consideration when performing 
resistance checks on a set of hand warmers.

For example, if a customer has a concern that the left 
hand warmer appears to be cooler than the right, the 
technician should compare the resistance readings of 
each pad to the specifications, and then between the left 
and right pads.  If the resistance of the left pad is 
significantly higher than that of the right, more current will 
flow to the right side.  While more common reasons for 
this can be attributed to how the customer holds the bar 
in their hands (fingers on brake lever and not wrapped 
around grip, etc.), there may be instances where 
comparing the left and right hand warmer resistance 
values may resolve the customer's concern.

Another issue is when one or both of the element circuits 
shorts to the handlebar itself.  This can occur either 
because the pad was improperly installed, solder breaks, 
or if the grip moves on the bar.

Hand Warmer Resistance Checks

NOTE: Hand warmer pads do not feature a high 
temperature circuit.  On snowmobiles featuring a left-
hand control, high temperature is achieved by 
supplying power to both the low and medium circuits. 
On snowmobiles featuring console-mount controls, 
the medium circuit is the high temperature circuit.
