Zetor 3511 not starting- electical

firstly check the connections on both the thick battery leads.... they need to be clean and tight for a good contact... take them apart to check for clean contact areas

then test the starter
on the starter motor solenoid there are three terminals , the 1st big one has the battery lead connected to it , the little one is the signal from the starter button which activates the solenoid to connect the two big terminals together to send the current to the motor.....

if you bridge from the first big terminal (battery live) to the little terminal the starter should work ..you can use a screwdriver, spanner or even the engine oil dip stick.. you may get a few sparks, dont try bridgin the two big terminals together directly wiv a spanner ... you will get a lot of sparks and may weld yer spanner on which will destroy the battery and starter.....

if yer starter works ok your looking at faulty wiring to the starter switch.... the battery lead on the starter solenoid should have a small wire on the same terminal which goes to the ignition switch then theres a wire from the ignition switch to the starter switch then from tother side of starter switch down to the little terminal on the starter.

good luck
