GL1100 Coils are both good, NO spark on 3&4??
1980 GL1100 STD
I have no spark on cyl 3 and 4.
Swapped coils around and still NO spark on 3 & 4.
I also have an extra coil, that works, just not on 3 & 4.
So I think I rules out the coils, they are GOOD.
When I power test the input terminals where the wires hook up on each coil, I have power at all four points where the wire hook up.
Not the plug output wires, in the input wires.
On 1&2, its a yellow wire on one side, black/white on the other.
On 3&4, its a blue wire on one side, black/white on the other.
I've also tested the spark plug wires by swapping 3/4 over to the 1/2 coil, they are fine also.
Plugs are good as well.
What else could it be?
From searching around, maybe a pluse generator? Where is that located??
Any help would be great, thanks!!
