MZ 251 and CEV odometer wiring

Postby Fleishmachine » Mon Aug 14, 2017 4:30 pm

Hi guys,

I have a problem with my CEV ( electronic ) odometer in MZ251 - previous owner mixed a wires of odometer ( one is still not connected to anything ) and it doesn`t work. I was digging Internet and I cannot find any wiring diagram for those instruments - all diagrams are for the old mechanical odometers.

Is there any chance that anyone of you guys got a diagram or maybe anyone got a MZ with one of those instruments so we could find out where the cables should be connected - there are three wires: Black, Brown and Green, and at this moment Green cable is loose, but Black and Brown are grounded, so I believe that it`s wrong as usually it`s only one ground needed.

It`s pretty annoying as I was trying to adjust a carbs, but I can only listen to engine and have to guess if it work in right rev.

I will be glad for any help.

Best regards,
Nicholas
