Been having some electric problems with my 06 DRZ40sm. Battery slowly dying throughout a day of riding, until it can't start. This is my second battery, which I have to keep on a tender now. I did all the electrical tests that were described in another post, got to testing the voltage output of the stator, and I had 50v for a couple seconds then it dropped on all three wires to around 10v, revving could only bring it up to about 17V. The battery reflects similar results. Revving slighting increases the voltage, but only to about 12.9V from say 12.5V or so. Revving also does not affect the brightness of the headlight. Definitely seems like the stator is bad, correct? What are the visual signs that the stator is bad when I get it open? Any aftermarket suggestions?
