help please

hi new to the forum i just baught a 1978 kz1000 has 3000km on it bike runs perfect but no lights will come on aside from nutreal and the red light on the dash tested my headlights and blinkers the bulbs are good 2 front signal lights are off the bike head light tail light and blinkers wont come on when i plug them in and fire the bike up any ideas what may cause this?

check fuses under left side cover

did that there all fine tested with a ohm meter was wondering if there is a breaker switch or relay that may control power to all he light or shoud i maybe do the dreded and cut the wire harness open to see if theres a bad wire?

do you have power at and past the fuses, headlight switch,sockets for bulbs?
the black wire with yellow tracer seems to be the common ground for many things on your bike,maybe try running a temp ground to the engine cases or neg side of battery to see if its the problem

Time to whip out the old voltmeter and start diagnosing the problem.

You should be able to find a good wiring diagram in the filebase here.

Good luck!

have signals working now they just needed plugged in headlight switch for high and low was bad so i replaced ot with one the same now when i switch from high beam to low beam it blows the main fuse and the blue wire fuse ?black and yellow wires in the headligh is power according to my test light so under the tank where the 3 wires for the high low must be the trouble im still tryen to figure out witch is ground in the head light its yellow red stripe is it the same under the tank?

well according to pge 229 of the shop manual that black/yellow id the ground for every light on the bike. :laugh:
the black ground on bikes/trucks/cars on cars really used to jack with me being an electrician,i was used to black being used for power on the stuff i worked on for a living!

Good Fortune!

got them all worken now thanks for your help huys she runs like a dream turned out had a bad switch on the high low beam got another one and shes perfect as fasr as that goes now to get the carbs synced and it should be good for another 30 years lol

so now that everythings worken well is there a way to cut the battery out of the bike completely since it has kick start ?

Not really, as the battery supplies the energy for the ignition.These bike do not have a magneto.Why are you trying to isolate the battery?
