1987 gs450 ignition box wiring help

[Guest]

My wiring diagram is pretty much crap and I am trying to get a break down of the wires going to the ignition box. Does anyone know what colors go to wear?

All the information is in the manual.

Manual in the top table middle, wiring diagram in the top table right.

That wiring diagram is different then mine - colors are off and my ignitor unit has 7 wires that has a 6. I was able to trace where each one went.. Now the only thing I am confused about is my signal generator... It has 4 wires coming out
G/Y-> UNKOWN BY ME - IT RUNS UP TO THE IGNITION AREA, BUT I AM NOT SURE WHAT THIS CONNECTION DOES
G/W -> IGNITOR (STAYS GW)
BLACK/W -> IGNITOR (BLACK BLUE)
BROWN -> IGNITOR (STAYS BROWN)

If anyone knows what the g/y goes to please let me know :-)

Welp figured out the g/y is for a oil indicator I think

Green/ yellow is starter solenoid

Green/ yellow is starter solenoid

Green/yellow or yellow/green?

Suzuki did a pretty good job of keeping the color code consistent across all the models. On the 850, green/yellow (green wire with a yellow stripe) is, in fact, the wire to the oil pressure sending unit, so I would guess that is true for the 450, also.

No idea why that would be running to the ignitor, unless it is a safety shut-off in case of low oil pressure.

Wasnt running from ignitor - it was coming from the same connector as the generator.. And a little tip for anyone if you have a downloaded service manual you can rotate the screen and it makes it readable haha

You can also click on the + button to enlarge it to make it even MORE readable.

Also helps if you are using a real computer, not a "smart" phone.

Green with yellow tracer on a 450 coming from under the timing cover is definitely the oil pressure sensor... the sensor is under the signal generator plate.

Im looking at the diagram and I am a little confused about which wire on the ignitor feeds it the power.. I beleive its the orange/white, but I cant see where there line links into the power from the battery on the diagram

[Steve]

Yes, it is the orange/white wire. The other end of that wire is at the "kill" switch.
