Does anyone know why a Powerlet branded battery harness with a coax plug wouldn't work with a Gerbing heat controller? I have a new out of the package Powerlet battery lead hooked up and can't get any power to the Gerbing controller. 15A fuse changed and still no go (original fuse looks good). Would the Powerlet lead be reverse polarity? Both of my Gerbing controllers worked perfectly the last time they were used on a different bike. Head scratcher!
