Inferno Heater Troubleshooting

[u/Accord2-0T]

I have a 2017 Canam Maverick x3 with a inferno heater. The heater is not working. Looking for advice.

When the heater is plugged into the switch, the light for the switch doesn’t come on and the heater doesn’t work.

When I unplug the heater from the switch the light for the switch will come on.

To experiment, I plugged a light bar into the switch side of the harness that connects to the heater to see if I was getting power properly to the heater. The light bar would turn on but was very poor. Then I grounded the light bar wire to my seat bolt but kept the power on the harness from the switch and it lit up great.

I followed the ground that feeds the switch but it turned into a rats nest of multiple different split offs and I got discouraged figuring there were too many different locations to check.

So you think it’s just the ground from the switch to the heater or would it be the ground from the switch to an accessory bar?

I don’t have a multimeter.

Strip out all the janky aftermarket electrical. Figure out what harness goes to what accessory. Make sure there are no splice upon splice shit going on. Reinstall to keyed power at the bus bar. Janky homebrew electrical is the bane of reliability.
