Fortunately I am carrying a spare, and have time to get it fixed.
Long story: I bought my 05 last September with 16K on it. The previous owner had installed an Electrosport. At first I thought that was good. Then after reading a bunch here, I realized it wasn't so good. I bought Eric Vallaincourt's used stator out of his old motor (stock stator) so I could have a spare on the rally. I also bought a gasket and threw it on the bike for the rally. Why didn't I just install it when I bought it? I dunno...theory about the ESport was, if it ain't broke, don't fix it.
Saturday, on the way to the rally, it was cold across Wyoming so I put on my heated jacket. When I got to the end of the ride in Cheyenne I was having problems with my Autocom so I started digging in to the farkle crap under the seat. That's when I noticed the headlight flickering. Hm...turned off the motor to stop the flickering. Tried to restart the motor and couldn't. Finally I looked at the Datel and saw 11 volts. It dropped to 10 or 9 when I hit the starter button. At first I thought something was wrong in the farkle wiring, since the Autocom was jacked up too. I got all the electronics ship-shape, saw the voltage rising as the bike was off, and decided to wait until morning to start it.
In the morning the bike started and I hit the road. All systems were fine, but I watched the Datel like a hawk. I saw the battery charge climb from the 12s into the low 13s...up and up, but very slowly. I run low-beam-only HIDs for my main headlights, so I was able to turn them completely off to help the battery charge. Finally after like 250 miles it seemed to have charged as much as it could. 13.9 with the lights off, 13.7 with the low beams on. Usually it runs 14.1 with the lights on...this ain't good. Very slow charging and not high enough. As I rode I thought about why my battery had discharged yesterday. I had originally thought there was some short circuit in my farkle wiring, but that didn't make sense. The wiring was fine. I realized it was probably the Electrosport starting to fry.
I called GZ, since he has some stator experience. He told me about how they build resistance going across connectors. My stator goes through a butt splice before it goes to a spade connector. That's three crimps between the end of the motor and the R/R. Then I called Hal, who told me how to measure the output. When I got to Des Moines I tore into it and made the measurements. I got between 40 and 45 volts on all three wires. Never the required 50 that Hal says the stocker develops. He wasn't sure what the Esport should measure, but presumably more than stock. Thereby confirming my theory. Stator starting to fry.
Fortunately I already have a service appt at the local Yam shop. They were just going to mount my new tires that have been sitting here in the garage for a month. Now they are installing a new stator. I am bringing them the necessary parts. I really, really hope that a) they don't fuck it up and B) they don't cause any new problems. Will ask if I can work alongside in the garage because my complex farkleization will make the job more complicated. Will also have them load test the battery just to make sure it's not part of the problem.
What am I missing?
