Diagnostics

If the starter does not work, first check whether its wires are connected to the battery wire. If the connection is normal, turn on lights or sound. Dim lighting or quiet sound indicate that the problem is in a discharged battery. Another option of starter diagnostics is removal of the wire from the terminals "30" and "50" of the ignition switch and connecting them together. If this will run the starter, then the ignition switch needs repair. Otherwise, connect an additional wire to the output of the solenoid starter switch. Now you need to touch the "plus" of the battery with the other end of the wire. If the starter does not run after that, the repair cannot be avoided.

At a service center the starter diagnostics will be run on the test stand. First, experts will check individual elements for operability and then proceed to the diagnosis of the starter with the test equipment.
