Re: Insane, growing, electrical problem
I'm going to take a different path here and say the problem may be with your battery. If it measured 11.75V at rest, after a 1/2 hr. of riding or not, it is dead. LIke, almost ZERO charge.
A fully charged battery should read 12.6-12.8V, not 12.4. And if you measure the voltage right after taking it off the charger, you are reading a "surface charge" which is inaccurate. The battery must sit at least 1/2 -1 hr. to let this dissipate and then you will get an accurate reading of it's voltage. And if you let it sit 24-48hrs, it should maintain that voltage. I would check your battery's resting voltage again after you remove it from the bike or disconnect it. Then charge it completely, and then get it load tested. It may have a bad cell causing your charging voltage to go all over the place. I would also hook up anther good battery, even an auto battery, to the bike via jumper cables (being careful not to short anything out against the frame or each other) and measure your charging voltage again at slow and fast rpms to see what your system is putting out, before you start digging into it. If your battery checks out good with a load test and holds it's charge, then the problem is elsewhere. Likewise for the voltage check when you hook up a good battery and run the bike.

As I wrote in my first post, I did do the OHM tests on the stator. The results looked good. As for the 'no load' test, well, that'll have to wait until I get power and can test with it running. One thing I am not sure of though: on the 'no load' tests, I know that I should test for 60V AC, but how do I do that? Do I need a ground, or do I check between pins from the stator?

My fault, I worded that part a little strangely. After riding, the voltage was low. After charging, the battery stayed at 12.6 to 12.7, even after sitting for months! I didn't put it on the battery tender until the end of December when the temps got really low here. I like your idea of testing with another battery, though. If the bike battery does have a problem of some kind, that would show it up. But, like the static test on the stator, that'll have to wait until I fix the power problem so I can get it running.

Thank you. Sounds easy enough to do, once I get the power issue solved so I can get the bike started. I'll be tied up all day tomorrow, but after that I'll have a few days to focus on this. |

I had an intermittent stalling and ill running issue and would occasionally. blow a main fuse with my GPz a few years back. It all of a sudden appeared in the spring (ran fine the prior to winter storage). I was thinking a bad connection with respect to ignition/spark. It took me a month of time consuming disassemble to finally find the problem. friggin MICE had chewed a small portion of my fuel injection wiring harness, i didn't see the damage until I removed the tail section and pulled the wires away from the plastic inner fender. Several wires were chewed right to metal and shorting out ! I was so pissed ! Now I am on a mission with mouse traps !! But as an example you can see how frustrating electrical problems can be, especially "ghost" electrical issues than are intermittent.

Re: Insane, growing, electrical problem
The benefit of that compared to poison bait is that you know where they are, instead of going to some hidden place to die and then having to track down the smell to find them.
