Anyone have any thoughts what could be causing this?

Synopsis:

Pulled wiring harness, inspected, taped, and wireloomed it.
Replaced stator thinking that was the issue.
Replaced thumb and hand warmer dials

[FONT=&quot]I put on a couple hundred kilometers after replacing the stator and wires with no problems. Now it's completely burnt again and it only took around the 50 km I rode this weekend[/FONT]
 

Boy you shure move around allot ...getting closer to me lol.Whats the plug for john, like were does it go.
 
hahaha, I have moved around a lot over the past little while. I bought a house here in Colgan so ill be staying put for a while now!

There are 3 white wires that come out of the stator which terminate at the burnt up connector. I'm pretty sure they head over to the rectifier from there, but that's just me reading the wiring diagram.
 
It could be the connector itself caused the problem. If the metal to metal contacts in the connector get oxidized/corroded, the connection will heat up due to the electrical resistance. Most often the connector is carrying low power but in this cause this connector handles a lot of power. I've seen this cause and effect on many electrical connectors. With the age of these sleds, some amount of corrosion/oxidation can't be avoided. I have had intermittent electrical connections with my fleet of vintage sleds 1993 to 2003, always found the problem to be a corroded connectors. Often unplugging and pluging in the connectors solves the problem. If there is room and you have a small pick type tool, you can often release the metal connector from the plastic connector boby so you can take a wire brush to it. I like to use a small amount of dielectric grease on the connector to prevent further oxidation.

When I replaced the stator it came with all new connectors, so they were pretty much brand new. I also used dielectric grease and even siliconed the back of the connectors to prevent any water from getting in there.

Im wondering if the rectifier has a ground and maybe that has gone bad? Would that cause a wire to heat up and melt?
 
Ya I know the big church there well...did you check the wires that go up to the cdi I have never seen it but some say they rub there by the footrest I think.If the connecter is bad could you cut the wires and put a new one in ?Or did you do that already.Put a meter on it and check wire resistance or if they are grounding out.


So if the wires are off the lighting coil there could be a short under the seat to the taillight or under the moter or at the bend were the hood opens to the headlight.

I managed to get close to 7 acres not far at all from the church, close enough to hear the bells ringing, which is actually quite nice.

Ill cut the wires replace the connector and test resistance. If that leads me to something Ill follow the wires back to the rectifier and see of I can find a rub through or some type of short. If all else fails I guess Ill just replace that rectifier completely....
