88 Ignigiton wiring problem

I got an 88 gs450L from a buddy of mine who had taken the wiring completely apart. I've wired most of it up, but I can't figure out the wiring for the life of me. Coming from the motor/pick up coil is three wires. A brown, a green/white, and a black/white. Now on the ignitor unit there is a black/blue wire and a black/white wire. Now my question is for a simplified wiring setup which wire does the black/white wire that comes from the motor go to? And does one of those two wires get grounded?
 
Trev,
Welcome to GSR.

I am not familiar with the twin engines. I understand that the wiring is different than those I
I am familiar with.

Search for bassclif bikeclif Suzuki website, maybe is a schematic there.

But I can say that blk/wht wire is typically a ground wire.

Would be good for you to introduce yourself in Owners. Include picture.
And put location in profile (UserCP)

Two "f"s.

Yep, there is schematics for 450s.

ignitor has more like 6 wires.
And signal generator 3 wires connects to it color per color.

Not sure on colors but there are two different ignitor's when you get up in those years.

Its something like this

1 ground
2 power
3 coil left
4 coil right
5 pickup 1
6 pickup 2
7 pickup 3
And coming from that side you also have an oil pressure switch wire.

The second type of ignitor has the same thing but the oil pressure switch also goes into the ignitor.



Looking at the haynes manual for 450's in general.
Page 225,226 has:

1 ground (black/white) has a ring terminal and is the shortest wire
2 power (orange/white) This orange white also powers both coils
3 coil left (white)
4 coil right (black/yellow)
5 pickup 1 (green/white) right pickup.
6 pickup 2 (brown) left pickup
7 pickup 3 (black/blue) neutral between the two coils.

Orange/yellow is the oil pressure switch.



Measure what you get for resistance between all the pickup wires.

That black/white from the ignitor might be a faded black/blue!

From black/blue to either brown or green/white you should get 60-80 ohms.

Also check each one to ground as well, it should be open.
