I'm just about finished up, but I'm trying to troubleshoot an electrical problem I'm having where the starter motor kicks on seemingly randomly when the battery is hooked up, even if the key is not in the on/run position. I have done quite a bit of troubleshooting and this is summary of what I worked on last night.
I took a better look at the switches and they had definitely been into before, cut and re-soldered. Luckily a friend has 2 bins full of old Honda controls/perches, so last night I swapped for a different set. This set has an OFF/ON/OFF switch that mine didn't, I was able to find a home for each wire except a 2nd black and a black/white stripe from the control. However, it seems that everything works on that side with the extra wires capped off. Also this one has the addition of the front brake light switch, so I'll have to figure out a way to work that into the existing wiring.
So after all this messing around, I'm still having the starter kicking on all of a sudden, I think it might be the solenoid. I was thinking solenoid since I was also only getting intermittent success with the blinkers. I tested and then replaced the blinker relay with a working one and when I connect directly to the battery, the switch and all the blinkers work fine. However, the blinker relay on my bike gets power from a cable connected to the solenoid that doesn't seem to be getting steady power which seems to support my idea of the solenoid. Today I'm going to double check all the wiring to/from the solenoid for shorts, otherwise I'm not sure what direction to go. All of the wiring in the switches seems good now and I figured out the headlight, it was in the bulb itself, just a loose connection.
So, I'm looking for ideas about what might cause the starter to have a mind of its own, and how to wire in a front brake light switch that wasn't originally part of the k0 wiring.
