I've got a
First Gear dual portable Heat-Troller. Red channel for jacket liner and yellow channel for gloves or glove liners. Last week I thought I'd fried the red channel getting off the bike and forgetting to unplug when I walked away from the bike. The jacket liner no longer got warm. I bought a new Heat-Troller and, to my chagrin, still no liner heat. I sat down in the house with the liner and an electrical continuity meter. The red channel was an open circuit. Thankfully, the
Powerlet RapidFIRe liner has an internal zipper that gives you access to the bundle of wiring inside. I traced the open circuit to a fault in one of the wire crimps. Cut it out, put in a new butt splice, and presto! Jacket liner is now working again. What to do with the extra Heat-Troller? Well, I may eventually invest in heated pant liners and heated boot liners. Then I can truly ride down to some low temps and for extended hours.
