NO START NO SPARK

[Gravity1073]

Hello fellow Wing owners. I just joined this forum. my name is Matt, heres the deal; i own a 86 GL1200A i got this bike as a basket case..i have no spark at the plugs. brand new battery fully charged, no voltage at the coils, starter relay solenoid is toast..got a new one on the way. PG's test out okay. stator? (three yellow wires next to the battery) test out okay. i dont have a service manual or any wiring diagrams, im looking for some direction. anybody?

Here's a schematic.If you have NO volts at the coil (12 vdc) look with a test light at the cutoff switch next to the starter button.It should have volts when the key is on and it passes it directly to both coils.
Also the pickup coils are attached to the harness right next to the 3 yellow wires(stator) you fixed(I hope).left side of battery.

hey thanks for gettin back to me so quickly! no good. no voltage at the kill switch with the key on. where is this main fuse? on the starter relay? and on the stator wires...i just pulled the connector and checked resistance from pin to pin.

Yes,the main fuse is attached under a cover on the starter relay.Just on principle we usually replace it with a waterproof 30 amp fuse holder and fuse.Let me look into the wiring to find test points and procedures to follow.I'll get right back

OK here it is.If the 30 amp dog-bone fuse on the starter relay is bad there wont be any power at all.Power goes direct to the ignition switch on the red wire.

It leaves the ign switch on a black wire

black wire feeds fuse #4

leaves #4 fuse on a black/light green

goes to the stop switch black/light green

leaves the stop switch black/white and goes to the ignition.

Test light each wire.It stops somewhere.

let me know if this helps.

The plug for the stator is a known weak spot.It has a tendency to corrode,causing a voltage drop at the contact point and then overheating and arcing.We(I use that term somewhat loosely) will cut the plug completely off and solder the wires together one by one.

Stators and regulators have been cooked by a arcing connector.This plug has to carry up to 10 amp on each wire.I just don't trust a 30 year old connector to meet the needs.

found the issue!! broken female terminal on the blk/grn wire on the big black connector to the ICU. got voltage to the coils..got spark..went to turn it over and the battery is dead! Damn! thanks for your help! -Matt
