I had the headlight problem and found it (after much studying of the schematics) to be a white wire under the seat and gas tank had come unplugged.

WOW! Finally an Actual Answer and know cure (At least one fix)! I have seen that wire and of all things would have never "Connected" to a headlight! (Pun intended)

I think the white wire is part of the stator bundle of wires...maybe a lookee there will help.I think its under the tank on the back of the engine...not the easiest place to get to.Maybe oil has crept into that connector.

Had a chance to trouble-shoot today, still no luck.
I found the white connector both in person and in the schematic. I checked the alternator output again, this time all the way to that connector & all three phases read 115v again @ 4k rpm.
I checked from that connector to the j-box and it was good. Re-checked the j-box by the manual using a battery and without and it tested good.
Thanks again guys for the suggestions, I'm finding everything it ain't !!

Dan - This is all weirdly familiar...

You say you've swapped out the junction box, and I hate to ask, but was it a known good unit?

Someone on .org had the same problem, went through all the same steps, even testing the junction box which, if I recall correctly, came out fine like yours has. I think the guy was about to torch the whole mess until someone else sent him a known good junction box, he figured he had nothing to lose by tring it and that fixed the problem.

Sometimes I wish I'd link threads like this - just in case...

Edit - I just re-read your initial post and you said it was a known good unit. Never mind...

That thread is currently on the 1st page of the 12r section at the org.

I have an extra known good j-box if gunner doesn't. Share your knowledge when I'm in need and I'll send it to you for free.

Wow, this goes back almost three years.

I never found out what the problem was. After getting frustrated to death I took the bike to a local dealership & they contacted Kawasaki and let them know the bike had the recall done on the stator / rectifier connection.

I about passed out when they replaced the stator, wiring harness, rectifier & junction box all at no charge. The bike was 6 years old with no extended warranty.

Needless to say I was impressed and thankful that Kawi stepped up.

those junction boxes are whores.. they use that SAME exact one on all the 90's and early 2000's 600s, the 7-R the nomad and other cruisers, the 12-R, ZX-11, ZZR's.. just about everything.

i'm working on a solid state conversion for my 7 to take out the MR301 relays and replace them with something fail-proof.. gotta find a compatible relay. the MR301 form 1C relay was a special-made relay with (for some stupid reason) a 9V coil and regular old dry contacts like a mass-produced commercially available unit. not sure if that particular one had any more kawi-specific tweaks, but i know theres a SS relay available. just gotta find it.

my 7 won't start sometimes.. a little rap on the black box kicks her right over.. lol the contact life is supposed to be 1 million cycles and almost o contact bounce..

no clue as to why they fail tho. the headlight relay is the exact same relay as the starter solenoid control power relay. they're both the MR301 relay i've come to know and loathe.

wierd shit about the headlight tho.

Just a thought I had the same problem on my 2001 zx9. I changed the fuse box with no change after a few days of deep thought I changed the voltage regulator and that fixed it. This all happened 4 years ago no problem since.

I guess I have the black cloud following me around, because the headlights on my 2000 ZX12 went out last week after a short ride went back to start it to go home and no lights. I had lights when I parked it. I know this because I was in a prking garage. As stated before I had the same problem on my 2001 ZX9. Its begining to be a large pain in the......

I was lucky on this one it was only the fuse in the battery compartment.

Well my battery went dead on my bike. Installed a brand new battery and now the headlights dont work. Checked the fuses and all the grounds. Not sure where to look for the relays to check or how I would hardwire it. Bulbs are good still.

I rode it during the daytime and the battery went dead. I am now guessing its either the stator or the rectifier.

Ok, I changed the stator, rectifier and reinstalled the new battery. I took out the two relays behind the gauges and they both had a multitude of dead spiders and their webs in them. Could that make the headlights go out with a bad connection in there? The right front turn signal just went out as well.

Ok, I took every relay off the bike, recharged the battery (again), took all the fuses out and took the J Box apart to look at the relays on the back, put it all back together and the right turn signal works again, but still no headlights. Would this headlight issue be related to the BRAND NEW stator not charging the battery?

have you jumped past the relays in the junction box to assure it is not the culprit?

Get yourself the schematic , the fuse for the head lights is located in the junction box/fuse box. You can get yourself a relay at your local electrical supply store, get yourself a low wattage soldering iron and replace the relay.

Just get the numbers off the old relay, Someone posted up the schematics on this forum a few years ago, I am sure if you research it a little you can still find them.

Good luck.
