'06 Wee electrical gremlins fix

My '06 Wee began to develop strange electrical issues several months ago that left me befuddled. Activating the turn signal would cause engine surging and sometimes stalling. As time progressed, using the brakes would cause the same issues. Finally, the engine starting system failed to work. By that I mean that when I would press the starter button, all electrical systems went blank. I suspected a grounding issue. I was correct. The culprit was the single conductor connector that originates about 8" from the negative battery cable. This is the B/W (~12AWG) wire that supplies a common ground from the battery. It even supplies the ground for the ECU. As I was attempting to replace both battery cables, I had a difficult time disconnecting this single-wire connector(B/W colored coded wire). Once I got it apart, I discovered that this connector was EXTREMELY corroded and was preventing a solid ground for all of the components. I had to cut this connector out since it was all but destroyed from corrosion and replaced it with a WAGO connector and fresh marine grade tinned wiring. Problem solved. I offer this experience in the hope that what I struggled through can help others avoid this frustration. No matter what motorcycle you own, if it is old and starts having strange electrical issues, check this ground connector first. Then, start looking for not only ground connection corrosion, but connections on the positive(hot) side. BTW, I also had to install a new starter relay. Any old motorized machine will suffer from electrical issues when connections haven't been cleaned regularly.
