Motorcycle Questions? Ask a Mechanic.
Hi and welcome to JustAnswer, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.
Initially, is a standalone volt/multi-meter available?
Let's try check and review the basics. Proposed preliminary tries (if have not been done):
In most instances, it would be a regulator that has failed.
However, if left unchecked and over time, the stator gets cooked causing a short to ground with any of the 3 or all of its windings.
The end result would be a replacement of the stator and regulator combo.
The regulator would still be a suspect then.
Also and even if just for test purposes, consider hardwiring a secondary ground line from the battery's - terminal to the frame, then also to the engine and to the harness ground/black wires.
And perhaps the article HERE may provide insight.
Very significant findings!
In both cases:
...were the stator wires connected to the regulator?
Can you please provide clear closeup pictures of:
Appreciate the pictures.And would appear several connectors? ...extension wires?Let's go back and re-trace our steps/checks:
To ensure that the readings are taken from the wires themselves and not at the pins/terminals of the connectors, carefully use safety pins as extensions of the multi-meter test probes to be able to puncture the wire insulation.
I understand; when able.
Actually, I am inclined to suspect:
