MZ/MuZ Riders

Discovered my tail light isn't working, bulb is good, just not seeming to get power through the grey wire that feeds it. Any ideas where to look for a bad connection up front? My eyes rather crossed looking at the wiring diagram trying to figure out where that wire reappears after disappearing into the harness. Headlight works, brake light works, just lacking juice that powers the tail lamp. Its a Sport Cup. Any ideas where to look are appreciated.

here is a drawing i have thanks to tony idle from several years ago

put main switch in park position if you have a front parking lamp and instruments

i would suspect the diode in the upper part of the drawing

Does anyone know where to get, or the model number for, the light switch for the rear brake pedal? My Skorpion Sport's brake light works for the front but not the rear brake. I suspect the switch is busted.

front is Aprilia or bmw r80 abot 82 83 r65 bmw maybe the 72 to about 75 HD AERMACCHI ss250 ss350
FOUND SWITCH AT BMW SHOP
BMW NUMBER= 61 31 1 244 070
front brake light switch
FITS BUNCH OF STUFF bmw apperlia ktm


Hydraulic rear brake light switch for Skorpion Tour (maybe others) is Aprillia #81244679. Thread is 10x1 mm.

probably same for other mz/muz

It's a pressure switch isn't it. You just need to match the threads with any banjo bolt pressure switch. I think the threads are M10x1.00. A post I read said to avoid Japanese shops because most of their switches are threaded in M10x1.25. Go to a Ducati or KTM dealership or order online.

BACK ON TOPIC

check plug on harness from switch and wires on back of switch they have been known to come loose

oh , i know , lift the tank off , up front on the right ,there's a small black plug,9 pin i think , its loom will look all bent where its hugging the side,,pull it out and youll find one of the double black wires broke loose,,fyi,if you have spare computer flyleads,,the crimps are the same,i just soldered it back on , alls good

Can anyone confirm the threads? I need a Front new master cylinder and a banjo bolt pressure switch since most available are like this.
Thanks

recently i had the same problem. By any chance did you recently unplugged the front pilot lamp?
If you did and switched the plugs you may have shorted some wires.

If not adn you want to replace the diode the rating is 6 amps 400 volts more or less P600B or highter.

What I did is took out the wiring loom and checked the wires one by one. they are prone to crackling.
If you dont want this I suggest to trace the offending grey wire from the rear to the front.

This is a dead thread, barko 1 the poster hasn't responded to anyone answers so why bother,Hate selfish posters,,others on the forum could have learned from his bike issue,,Anyway, i had the same fault and posted fix here,,didn't say whether it worked for him or not.

cmg241... I just ordered a banjo bolt pressure switch for my 95 Skorpion. I can confirm the thread size when it arrives

I purchased this on Amazon as an almost act of desperation and it works! Cheap money and it included a clutch lever I did not need

do save the lever for the future.
if you do not have a broken one in your collection ....
WAIT a few months

Crap Dave I used to race an R6 on one of the most dangerous tracks in the US, NHMS. I once broke two in one day The nice thing about supermotos is that they weigh so little compared to "big bikes" that when they do fall, they do not tend to break nearly as much. I was taking her Baggy to a track day this weekend but had to bag out just today due the flu..

when one of my MZ bikes falls over it always breaks a lever
its been setting for a year and broke the clutch lever when it fell over in the shop
when the sidestand collapsed for the 3rd time since it was new in 2002
