Please help explain this

Ok, After a short ride to breakfast this morning, went to get back on the bike, fired it up, looked down to kick up the stand, and saw smoke rolling up, so I shut it down. After a closer exam, i found one of the yellow wire connections from the stator was black and melted, but only one of them. After getting it home, I re-do the connection, look over everything else and find no other damage. Fired it up with the volt meter on battery, and still seems to be charging fine.

This is a 2003 w/ 12K. A mosfet r/r and re-wound stator that was changed back in winter 2011 with no problems since then.

Any ideas are appreciated as to what happened or what may be happening. thanks,

It was probably a corroded or loose bullet connector, or the insulation chafed and shorted to ground.

X2 on that, did you use dielectric grease on your connectors when you changed them out last year?

Hey guys, appreciate the replies...although I dont believe any of the connections were bad in any way, I guess anythings possible. I used quality connectors at all points when re-doing the wiring, and the bike gets garaged. I'm starting to wonder if the heat of the day had any effect on the stator as I've read some other post where folks are having issues b/c of the heat. Anyone else have ideas?

I'm with them. This happened to the bullet connectors on my 90 the day I got it as well.

I bypassed the bullet connectors, and soldered the wires together. Probably the way to go.

Update

Hey, just wanted to give an update for those who may experience this down the road. I've seen a number of post of folks who this happens to, but no follow ups or explanation as to why it happens.

Anyway, after re-doing the smoked connection, I pulled the connections apart and checked the Ohms across each one(while the bike was cold). All clear. Reconnected wires. Fired it up and let it warm up to normal temp. Seperated wires and checked Ohms again, all read the same ".ol". So, here in the next few days, I'm hoping to road test and see if anything happens. Probably gonna leave off the side cover just to let a lil more air flow thru to wires/battery, etc.
See ya down the road.
