I have a problem with my handwarmers on my 1332 pro ariens. Neither grip gets hot, but i have power in and out of the switch as it should. When i put power through the left grip, i get power out. when i put power to the right grip i get nothing out. yet neither get hot...any ideas?

:welcome: to the forum

If your handwarmers are wired in series if one goes bad it will prevent the other from working.

I thought they were all wired that way until I tried to find a diagram and now I'm seeing some are series and some are parallel. If parallel then when one fails the other would still work.

The Diagram below is wired in series. This would explain why if one won't pass electricity they both don't work.

warmers

Thanks for the reply! these on my blower are wired in series. Even when testing them i get power in and out of one grip but not the other. Neither get hot. Is it possible to have continuity through the grip but still have it not warm up? just trying to figure things out before i buy parts

If you have a light on your blower, try disconnecting the light and wiring it to the hand warmers circuit, if it light works likely the circuit is fine and your hand warmer(s) are bad. You can also try connecting the warmers to a 12v source and see if the warm up (to make 100% sure that they are good or bad).

Check the grips for continuity. The one that is not passing power sounds like it is open circuit. Use an ohmmeter and see what resistance you get when you have one test lead on each connector for the suspect grip. Both grips should show the same relatively low resistance reading. If one shows a large reading, or infinity, it's open circuit, and either one of the wires is broken at the connector, or at the grip, or the heating element in the grip is open circuit.
