So my bike has always started and run fine. I was out riding and stopped to get gas. Went to restart and it was dead. Push started and got home. Tried to start again and it was dead. Put it on the battery tender and it was reading at 0%, but took a full charge overnight and is now starting normally.
I read a bunch of threads on here and got to work with my multimeter for the first time.
In DC voltage the battery reads 12.72 consistently while battery tender reads 95%. Reads 13.5 when it reads 99%. These readings are after disconnecting battery tender.
Battery current leakage: (by placing the multimeter between the neg battery post and the cable) shows 1.3ma
Regulated voltage: with a cool motor, sometimes I'm getting as much as 13.9 volts at the battery holding 5k rpm in neutral but it has to work it's way up there over 30 seconds or so. A lot of the time it shows 12.5-12.7
Generator coil resistance: resistance between the leads coming off the stator show 0.7 with all three test combos a/b, a/c and b/c.
Generator no load performance: current at the same three stator leads show 75-76 AC volts at 5k rpm in all three test combos a/b, a/c and b/c.
I think these are all saying rectifier is bad and the stator is good. Am I on the right track? Rectifier is in the stick position btw. I keep forgetting to order the relocation kit.
