How do I know if my tractor starter is bad?
A bad starter can manifest itself in a cranking noise without engine turnover, a clicking when the ignition button is pressed, or a mower that simply does not respond to attempts to start. An indication of a bad starter motor is the absence of other electrical problems that can be more easily tested.

How do you test a starter solenoid on a tractor?
First, turn the ignition key to the “On” position. Look for the large terminal posts on the solenoid where the thick red wires connect to the solenoid. Touch the metal shaft of a screwdriver to both of the large terminals at the same time. If the engine turns over and starts, the solenoid is bad and should be replaced.
Can you bypass a starter?

How much voltage should be at the starter?
Voltage drop on the ground side of the starter circuit should be no more than 0.2 volts.
