From what i read on another post, the two 'hot wires' are tied together at some point in the circuit and the two 'trigger wires' are the negatives that go to the ECU and open/close the circuit... maybe i need to swap THOSE two identical Yellow w/ Green trace wires rather than the two 'different' wires.

I'm about to go buy a service manual if i can't figure it out.
I'd just do it by trial and error but don't wanna fry any expensive little boxes.

Gonna go check for my hots with the ignition off.

(Yeah, i swapped the spark plug wires.)

Ok, messed around with it again and got it to fire off with the Blu/Org & Yel/Blu wires crossed.

That's not the issue. I have some kind of short... that is the problem.

In the process of charging the battery again and scouring the harness for the short...

hey capitalist.. from looking at my electrical service manual... here is the description of the cables/connectors:

Ignition Coil connector .............cable color ............. description

A ............................................. Y/GN ...................connects to Port B then to a System Relay
B .............................................Y/GN ....................connects to Port A then to a System Relay
C .............................................Y/BE...................... Rear Coil
D .............................................BE/O .....................Front Coil

it seems like the ones to swap are the cables C (Y/BE) and D (BE/O)

I hope this helps...

Don't know about Sporties but on my softail I just swapped the wires at the connector coming from the ignition module. Didn't have to cut and solder anything.

Post update

I've pretty much narrowed it down to the battery.

I'm hoping it's just a coincidence that the battery took a dump on me while i was doing this mod. Going to the dealer tomorrow to get the battery tested. The bike cranks up fine with the battery on the charger with the wires in the original place or swapped (with plug wires swapped accordingly). When there is an issue the started solenoid makes that ugly clicking noise that denotes inadequate amperage.

* If the battery tests good, then it's obviously a short causing the drain. We shall see...

Thumbs up

Update:

Got the battery tested at Interstate, the Dealership (needed to get new wires anyway), AND bought a tester.

3/3 testers, battery is fine.

Got the rocker wires on and the bike has been running fine ever since

All I did was swap the two coil wires and everything worked great no crossed plug wires
