Hey Knot - hope all is well - I installed one of the first versions from Jake years ago - had bike on trickle charger - charger light was flashing red and had no power to anything - replaced battery as it was pretty old anyway then realized there is a black wire with a 15 amp blade fuse that keeps blowing when bike is keyed on - cannot for the life of me recall what a black wire with a 15 amp blade fuse would be for (possibly the scorpio alarm) but still no power to anything - will be putting the bike up on the lift and digging in deeper this weekend - was hoping to have the diagram by my side as a guide, if needed.
