i got another Wr 500
Im having a problem with the wiring
On the coil,there is 1 wire that plugs in to a wire that has 1 lead and a ground wire
Im sure the ground wire goes on one of the screws that hold the coil to the frame
When I attach the wire,I get no spark,when I leave the wire not hooked to anything I get spark
Its a simple wire job,but what am I doing wrong?
Anybody have a Yz 490 or Wr 500 that can check where the ground wire goes,,and why do get spark when its not attached?

Does that wire go to the kill switch?

No,it plugs into a wire from the CDI

im pretty sure it goes to the voltage regulator, make sure your kill switch works properly and just tape it up and dont use it

Kill switch works

It goes to the kill switch, and then into the wiring harness. The eyelet end goes onto the coil mount bolt. All the wires should have the same colors, usually black with a white stripe.
