ok wire questions,, HELP!!

OK so my evening is ruined. for the first time my lady wanted to go for a ride so i put the battery on the charger to bring it back to peak so we wouldnt get stuck anywhere. ok here is a problem,, my center wire coming from the stator likes to heat up,, i just fired her up and was checking the voltage to see if i had enough juice to make it on a short 10mile trip i seen some smoke coming up from in front of the battery, when i checked it was my middle stator wire "cooking" the insulation i put around that bullet,, that wire is why i replaced all my bullets it cooked the original one also.

check that wire for a short where the wires go in between the engine and transmission....


Hope this helps you out some

well i am going to need to take off that heat sleeve and check those wires. already thought of that. i did a brief check last night and one of my wires coming out of the stator looks dark. but i dont know if its from being cooked or some overspray black paint from when the PO painted the engine. if i take that sleeve off what can i use to replace it with? i was already thinking that there might be a wire shorting out just didnt know how to check for something like that.

check the wire in question with a multimeter set to ohms...take the red lead o the wire in question and black lead to engine block ground...if the resistance is zero...u have a short....if you have numbers, you have a frayed wire...if it reads ol or nothing then the wire is good as for another heat shield...you can get some good quality shield at NAPA for about 50 cents a foot

ok so can anyone tell me what a bad stator looks like? i took the cover off to take a peeky poo at it and it was black and looked like there was a loose wire in there. going around one of the coils.

Here are links to a couple of shots of my fried stator:

Yuck! Good thing you switched that out! Yoshi, I think of it as way overcooked caramel - burned, in Chris' case. But it'll definitely be dark brown/black and look, well, like it was cooked a little too long.

Sounds like the wiring harness coming off the stator rubbed on the rotor and caused the short mentioned in your other thread and then the rotor proceeded to grab a wire and wrap it around the stator.
If the insulation is black and bubbly, one or more of the phases has burned out due to the short. This could explain the before and after oil change numbers you got as the wire probably let go just after the oil change. Whoever put in the new stator didn't check the wiring after they reinstalled the left engine cover. It's an easy mistake to make.

so basically your saying my stator is fried? it doesnt quite look like those pictures. close but not like that. and if it were a stator burned out why is it still charging my system at low voltage levels? im getting high 12s @5000 rpms. this is what is confusing a lot of people. they want to say a stator issue but at the same time with it still cooking the middle stator wire every now and then at the bullet and still charging they back up a little and say there is a short in a wire somewhere. i really need to find a mechanic i can make a deal with and do payments or find a way to trade services. I work at a distrubution ware house for high performance race car and muscle car parts and also truck parts. im willing to let a mechanic use my discount i get from there for the summer on parts they may need for other projects in exchange for fixing the motorcycle and letting me make some payments.. im grasping now.. i know,, but i need this done before my girl tells me i have to sell my new bike.

you are charging at low levels because you are charging in a 2 phase instead of a three phase environment. Your stator has three output wires...each wire represents a phase. you need all three to be producing electricity in order for your voltages to be right....

some one who understands a/c voltage production help me out plz...i understand the concept...just not how to word it.
