Bad Stator

[J-Madd]

At the end of a decent pass 2 weekends ago the engine died when I pulled in the clutch. The stator had went bad and one set of wires would not test for resistance (0 ohms.) Well, I noticed the part on the face of the stator assembly where the wires are soldered and epoxied had broken loose a little. I wiggled that, now it tests fine. Can I strip away the epoxy and re-solder/epoxy this?

 

 

Just inside the black line is where the piece is separated. The circle on the left is where the wire is exposed a tad.

 

On another note, the motor quit at the end of the last pass of the entire race last weekend (still made a good pass, just like before). Come to find out the pickup coil came loose (different stator.)

yes,you can.Had a brand new ricky stator that did the same thing,except it was an eyelet that cracked and would occasionally flex and the engine would cut out.I soldered it up,been running it ever since

yes, it can be fixed, but that wire is probably too cooked. take a heat gun/micro torch, and all that white coating will soften up enough to pick/scrape off. then pull that magnet wire up and check it going into that first pole. there actually should be 3 bunched together for strength. you should be able to see if one is cooked, or if it's salvageable. epoxy the pieces back together. if it's cooked, then you probably need to re-wrap the whole post.

Yeah, the wire is kinda burnt. It looks like just 2 strands of copper instead of 3 are still intact. I've already epoxied it before reading this. I'm gonna a try it on my bone stock Banshee, but I can't risk it going out on a race bike. Not worth losing a race over.

that one burned/broken wire is actually the only one it uses. the other 2 are dead wires added in there for strength.

We're talking about the same 3 tiny copper strands, right? Will it still test good if that wire is broken? I guess maybe it's making enough contact to test good?? I don' t mind installing it to trouble shoot, but if it's gonna crap out on me under certain loads or rpms, I'll try to get it fixed right.
