as i remember, junction boxes differ, not interchangeable between the Gens.

yes they are different, because the wiring is different gen 2's make use of the brown sensing wire, gen 1 don't [well euro models don't] so we can use a gen 2 fuse box on a gen 1 but not a gen 1 fuse box on a gen 2. it may well not be the case in the US not sure I will have a look at the connections on the diagrams later.

I pulled the the wire harness and the neutral safety switch oil pressure switch and kickstand switch wiring was messed up would that cause a no start or power to the cluster

No, interlock switches only deal with ground side of starter-relay, which activates starter-solenoid. You need power going into junction-box in order for starter-relay to send power out to starter-solenoid.


Pull out voltmeter and trace starter power-circuit from start to end. Key ON, measure voltage at these locations:

1. battery's positive terminal, what is this voltage?
2. white wire coming out of starter-solenoid, what is this voltage?
3. white wire going into ignition switch, what is this voltage?
4. red/blue wire leaving ignition switch, what is this voltage?
5. red-blue wire entering junction-box, what is this voltage?

What voltage do you measure at all these locations?
