bike wont charge...again

Stator is good. Helps if I read the directions. I was measuring wrong. The legs all produce up to 80 when revved.

there are more directions

The discolored positive lead to the panel is just grime. I sanded every contact and put electrcal grease on them.

OK , 80 volts leg to leg, now check leg to ground- you want none.

If you have 80+ volts AC at each stator leg then your stator is probably not the source of your charging problem. You can do a quick double check and check the DC resistance between each of the stator legs and ground. If you read an open circuit then you're good. Start looking at the R/R or wiring as being the problem area.

Best to do leg to ground test while doing the running AC test- the alternating high voltage tortures the windings more than the low voltage of a multimeter's ohm test. My last failed stator passed the ohm test, but failed the leg to ground AC . It was BBQ'ed upon inspection.

I guess there is always time to redo that, how does sanding contacts get inside of crimps? Answer it does not.

saved me from having to type that

If you do pass the leg to ground @5k rpm tests then redo the quick test to see if your numbers improve any with the clean up done.
if it improved the run the phase A tests where you measure voltage drops. It is possible you just have very high resistance preventing the battery from charging.

Found the problem. Two rubber sealed spade connectors were were side by side and had worn through the insulation. It was inside the harness inside a rubber boot inside a taped connection bundle. Life is good once more. Thanks for all the help and patience. Alot of other stuff is cleaned up now as a result, especially the fuse holders.

You are not done till you redo the Quick test and post the results

It's hard wired in with almost no slack left. It showed 13.7 charging. Maybe next weekend. Im revaling in the moment for now. I'll post a pic of the offending pair of connectors tonight. Sneaky liitle issue.

The sneaky issue showed up on the leg to ground but not the leg to leg test right?

13.7V means you have dirty connections between battery and R/R and the fusebox is the first place to start and don't get out the sandpaper .

I think I'll clip out the connectors and hard wire these two pieces.

Dont know what the wires go to, but they were sucking about 2 volts 2volts via the short.
