Help diagnose problem - KZ

Doogie

Been Around the Block
Trying to get a KZ550 H2 running.

Turn ignition on lights/dummy lights come on. Press starter button and nothing.

Bridge the starter solenoid -> sparks, and the starter turns over and that's about it.

The wiring harness has been messed with a bit by the PO but mainly around the head light.

This bike has a starter kill switch that mounts to the clutch lever assembly on the bars..does the clutch need to be in even though it's in neutral?

Will bridging the starter solenoid actually be able to start the bike or is that just a way to test?

What should I try next??

Thanks in advance.
 
Clutch needs to be in. I've got a kz750 and I had electrical issues in the starter assembly housing as well, a member suggested going through my electrics with deoxit dn5, and that made a huge difference. Hope that helps!
 
Right on. Thanks. I am thinking of deleting that kill switch. My best guess is that the starter switch is bad. When I push the button in it really doesn't go in but it looks like it still makes contact.

I've never heard of that deoxit stuff, I'll look it up.
 
Clutch needs to be in..here is a helpful wiring diagram in COLOR!! I used this to get my Kz50 running and delete the extra crap. I plan on making a new wiring loom this winter to go bare bones wiring.

Thanks a lot Gooch. Hopefully we can get her running soon. Would holding that clutch switch in by hand work?
 
It' just a contact if I remember correctly so yea. Jump it out but make sure it's in neutral. KZ was actually easy to work on especially with the color diagram. The original intent was to chase the neutral light problem I was having, I ended up ripping out a bit extra like "reserve lighting" module and some other extra stuff.
 
Yea we are just trying to figure out the issues and get it running asap but we will probably wait until the spring and redo the whole shabang over the winter.
 
Update: The issue was the starter lock out switch in the clutch. It was either shorting out, old crusty wires or bad switch. Turned out to be a bad switch. Anyhow, soldered it up, eliminated the switch and everything is up and running now.

Thanks to everyone for their input and advice.
