Been awhile since I've been on. Hope you're all well.
I've poured through some of the stickies on the topic, but I wanted to solicit some thoughts on my current charging situation.
FYI, I have a PCV and autotune on there, as well as BD-43s headlight mod.
Mine is an '09, had since new. Replaced the first Yuasa battery about six years after purchasing as it was losing charge pretty quickly.
I've had two replacement batteries since. Both work fine for a season, but then die out completely. Earlier this week, I had it die completely to the point where I couldn't even bump start it, though I had just ridden it about twenty minutes before.
Got a new Yuasa battery yesterday. Charged it up overnight on the optimate.
Today, I went out there with the tank off to do some measurements.
Sitting, key off, its at 12.9
Sitting, key on, its roughly 12.7
Started at 4K, its at 13.54
Measured the voltage from the rectifier when running at idle and is was 13.18. Will have to test again at 4K
Measured the resistance from the stator wires, but this is unreliable as my dmm seems to suck at ohms. Each time I touch the probes to find my base I get a different number. The one time it was consistently .7 on the meter with the leads together, I got .4-.5 on the various pairs of wires after subtracting. Wish I had a better meter.
Leakage test on the new battery showed no draw.
Does this sound like a rectifier issue at this point as it's not getting close to 14v under load? Any luck finding a quality cheap ebay part?
Thanks!
