Iím working on a new friends ET2. It is having ignition problems that iíve narrowed down to the main wiring harness.
So far Iíve,
Replaced the stator/ pickup
Replaced the CDI
Disconnected the kill switch
Disconnected the starter relay
Disconnected the key switch
Disconnected the stator from the main harness.
If I disconnect the main harness from the stator I have consistent strong spark at the plug. If i plug in the harness to the stator I have spark for a few kicks and then nothing.
So far as long as the main harness plug is connected it wont spark, regardless of what else is connected/ disconnected.
The green wire is the ignition/kill wire. I tested it looking for shorts to ground with my multimeter and nothing. Visual inspections came up with no visible chafing. Testing AC voltage at the green wire disconnected from the harness Iím over 60V AC when kicking. As soon as I plug it into the harness I get a spike of 20 and then no AC voltage at the green wire.
So, does anyone have any ideas on how to narrow down where in the harness my problem lies?
