I'm having charging issues. I've done quite a bit of reading, but have a few questions still.
I first noticed the battery wasn't charging. But I haven't really ridden the bike yet, so from my understanding, this bike won't charge the battery unless ridden for a while at higher RPM's. None the less, I still felt it important to test the charging system. I understand I should see a fully charged battery rise from 12.5 to up to 14 v when reved at close to 4000 RPM. I tested this with my multimeter and at higher RPM's I saw no climb. I thought I should do some testing.
Tested all 3 stator wires on lowest Ohm setting... Received 0.7 - 0.8(fluxuated quite a bit, but finally rested between these two readings). Apparently(from what I read on some forum posts), to zero a digital multimeter you touch the two leads together and subtract that reading from the reading received from the stator tests.
When I zeroed the multimeter(by touching the red and black lead together) I received a reading of 0.2 - 0.3
Am I correct in thinking that I should assume the stator test on all thee detached bullet connections in front of the battery, whatever those readings are, should be 0.2 - 0.3 less?
If so, is that not within spec and my stator is good? At which point I should look at the R/R...?
I did this test with battery connected and fully charged with the bike off.
