Help!!!!! Electrical issue
okay '95 Fatboy Stock. Driving down the freeway and all of a sudden hear what i would describe as something shorting out. pulled over engine died. Towed home and going over everything to figure out the issue. could use some insight on where to go. I will list what i do know so far.
1) No accessory lights
2) No Lowbeam but I do have HighBeam - Low beam bulb bad.
3) Rear Brake light functions but no running lights
4) No turn signals
5) dash lights function for neutral,oil,hi-beam indicator
6) Starter relay good
7) Starter Turns - no start
8) No spark at plugs
9) Stator is not grounded, Resistance checked good.
Where to go from here?
Just realized that all bulbs lit at the time of the short were taken out
The Turn Signal Canceller Module is bad so far. Havent even gotten to why i have no spark yet.

need to do all your checks with fully charged battery- otherwise you can get inconsistent results.
trace and check that battery cables are good, sometimes the insulation wears off of the + cable from the battery to the starter.
can you check that all of your circuit breakers are working< test light should light on both sides of the breaker ( both terminals) if they are good.
Looks like we are guessing that ignition module is pooched- got a pal with one in a box to test with?
I have one, I'm in PHX. ( put your city in your profile, you never know when the guy who can help you is 2 blocks away)
If your ignition module is bad, think about the crane hi4e, it's pretty good.
when you test for spark, make sure the plugs have good ground or you can blow the module while trying to test...careful

Updated profile to show location. Arlington Texas
Battery Is fully charged... just replaced 2 days ago. Yes i still verified proper voltage.
Performed the checks for turn signals bypassing the module and all worked fine so definitely need a new turn signal canceller. Anyone know a good cheap replacement? $140 for a new one from the dealer.
Ignition coil primary and secondary circuit test was within the specified ohms.
Ignition Module Resistance tests all checked good.
Coil checks that i have done so far.
with ignition switch on i have 12v at pos side of coil.
removed neg wire from neg side of coil- 12v on both terminals. Resistance checks were good.
Gonna make the jumper described in the manual to continue my tests in the morning to see if i can produce a spark at the spark plug and go from there.
Such fun when trying to learn from the Factory manual but Id rather do this than pay the stealer to do it
