10540 Wiring Issues

[z10540_steve]

Hello All, hopefully someone here has some 10540 Cab model experience. Lights have been lost, there seems to be no power going to the master light switch (bottom switch on LHS). Using jumper wires all the lights can be made to function so they are ok. We have no diagrams available, does someone have emailable wiring diagrams for this tractor. The black wire to the switch looks like the feed, red going to the relay on the RHS for lights, white directly to front lights? Is there a master control relay on this tractor that energizes the feed to this switch and other functions? Thanks.......Steve

Yes the newer models of the Zetor 's are famous for their wiring problems. I had the same problem on a 9520, after checking every wiring and not finding the problem, it turned out to be a loose fuse, the one that controls the cab lights. Whatever you do dont try and improvise the wiring it will only make it worse.

Cheers,
Lucas
