Hello everyone
I have an '85 K100 showing no electric power in any system. No power to dash, lights, starter, anything, no relay clicks, like there's no battery or circuit at all.
One year ago the bike was parked in my garage with fuel issues, but with good electrical power and would turn the starter just fine.
I swapped fuel injectors today and now no electric power in any system. No power to dash, lights, starter, anything, no relay clicks, regardless of key on or off, like there's no battery or circuit at all.
when I removed the fuel tank to inspect the wiring, I found lots of evidence of new mouse/rat nesting..but no chewed wires yet
-fuses are good
-Swapped "OK " battery with brand new battery and tested good with multimeter
-triple checked connections on battery and under tank, everything is tight
-checked dash wiring connection, removed and reconnected (the dash is in rough shape but powered on in the same spot a year ago..)
-checked grounds. Is there supposed to be a ground wire around the rear brake pedal?
-Bypassed ignition (key) switch a long time ago, I twisty tie red and green when i want to start it
-HALL and injectors swapped, unrelated
The headlights and brake lights are all currently disconnected, just as they were when I had good power a year ago
I had to run this $800 K100 hard through the troubleshooting flowchart when I first bought it so I have a decent grasp on the systems. Replaced the fuel pump, fuel/ignition relay, had to unstick the injectors, but I got it on the road.
Unfortunately that flowchart starts with good power/circuit. The bike is completely dark and I have no idea where to start here.
