rats, no spark on my new skunk

ok, so the p.o. had a kill switch mounted under the left side cover which killed spark. looked like a simple enough affair, basically like he interrupted the flow through the ground wire (the black with the crimp on bullet end, red and yellow ones in the pic). well i removed the switch and soldered the wire back together plugging it into the receptacle in the picture. i looked in my sevice manual but for the life of me don't know what the red, yellow and black wire originate or go to. no spark? i'm missing something here, suggestions? call the p.o.?
 
You should be able to figure it out with a wiring diagram. Don't you have one?

Did his switch interrupt the spark or prevent the solenoid from working? It's hard to tell from pic. The red wire might be from r/r to harness. Does it crank, but no spark?

cranks over like crazy, no spark.
 
upon further investigation seems like three of the connections have new crimp on connectors, red, yellow and black.
the red wire plugs to white, the yellow wire to yellow-black, and the black to a what appears to be what appears to be a blank receptacle that appears to be part of the starter relay wiring .
 
Yellow/black is for the fuel gauge, White is for various functions including feeding into the contact breakers (points) so that may be the key wire here.
 
the ground wire was plugged into the circled connection. does that seem correct? or is there another connection for the ground i'm missing?
what is the white wire the red lead plugs into, power? looking at the wiring diagram in my service manual shows no red to white connection. same for the yellow to yellow green.

Are the Red, White and Black wires from the ignition sensors? If so the red should be for power to the sensors and the black and white wires would supply the switching for one coil each. Ray

Ray,
yes that appears to be the case. would the red plug into white? i don't see that on my wiring diagram.yellow looks like it should remain yellow, not plug into yellow/black. the solid black wire, is it a ground?

If it is indeed for the fuel sensor then it is a ground.

It's hard to tell much by the pictures but is the black wire something the PO added or is it part of the stock harness? If it's stock it may not be a ground. Grounds are usually black/white. Solid black is usually a turn signal wire. I know I'm not telling you anything you don't already know as far as the colors go, just thinking out loud. You're probably going to have to break out a meter and explore a little to see what the purpose is and what they feed or feed off of. Red is the main power wire and white feeds a variety of things like tail lamp and igniter. At least on my 700 that's the way they are.

Sorry, you never mentioned white. I'll have a look at my diagram and see what yellow does on my bike. Suzuki kept things the same for years so it probably has the same function for you.

Edit: Yellow is high beam on my bike so it makes no sense it would be involved with a kill switch in your case. If you have a meter check the black wire and see if it's a hot wire. Touch red probe to the wire and black to ground. Of course the black would have to be hot with ignition on.

Skunks did not come with electronic ignition did they? If not, then what kind is on the bike? Is it a Dyna or did the PO completely redo the ignition system to install a later factory electronic?

Have you physically traced these wires to see if they go to the ignition cover on the right side of the bike?

I strongly suggest you try to figure out which wires are part of the factory harness and which ones are not. Figuring out where the wires run on the factory harness is easy using the wiring diagram in the service manual, but all these splices for aftermarket add-ons is what complicates the situation greatly.

Those red bullets are obviously not factory, and the Red and Yellow wires shown in the photos that seem to be grouped together don't look factory either. Most likely those are for the aftermarket electronic ignition so you need to know what each wire does before you start guessing on how to hook them into the factory harness.
