HAND WARMER DIAGNOSTICS

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.

FULL LENGTH HAND WARMERS

Full length hand warmers differ from standard length
warmers in that they are cut to match the bend of the
integrated handlebar hooks. Because of this, there are
separate warming elements for the left and right side of
the handlebar assembly.
To install, note the orientation of the hand warmer
element before removal. Reference the illustration and
notes below to properly install the element pads.
