No spark

Got a 421 4mill serval recently tore it down to redo frame, after I put it back together it wouldn't start so checked everything good and all was hooked up right, pulled everything but motor again cleaned all ground points and still nothing, so ran a ground wire from case to frame this morning as I was told that is probably my problem sneak I pulled harness and checked everything on it and still nothing so I am thinking it's either kill switch or coil? Ran perfect before im stumped! If their is any other info ya need please ask!

Checked pickup gap? Have you tested stator and coil with ohm meter. Also tested Kill switch with multimeter for continuity( should have none when on) or just unhooked it and left wires apart? is key switch wires properly spliced together if its bypassed. if its still on the bike  do so to rule out bad keyswitch?

Ok the red and black wires are for the key right?

yes sir. should be spliced together

[astewart]

It wasn't but it ran that way before unless they had something rigged before and I didn't catch it! so what does the red one go to?

[Starwriter]

The wires on the harness side of the key switch connector are red/black and black. Connect them together.

red and black go together. it must have had a jumper doing this or it could not have run previously

[astewart]

Shit! I new it wen I did it! I should have asked before I tapped all that stuff up! K I'll let ya no it works thanks guy!

[astewart]

Is the black a ground?

[Starwriter]

Yes, all black wires are ground and all are connected together inside the harness.

older style has just a black and red wire wich are tied together.( thats how my 89 is)  I think new style has a blk/red tied with blk/white and brwn tied with red. not sure how many diffrent styles there are but i know of those two.

[astewart]

K just making sure! It's a 01 and only had the 2 wires

cool, ya my 89 & 2000 has same deal but in my researching I found more then one style and wasnt sure when they started doing this or what year your bike was.

[astewart]

That's what it was! Thanks guys! Fired up on first kick! They had to have had a jumper in it and fell out!

Cool, did you end up just using a jumper wire or did you splice them? i got my bike and it had a jumper wire. under heavy load in rough conditions bike would sputter.  Took me days to figure it out. I chased jetting like crazy it was quite annoying. once i cut and wired them together it was fine.
