To test whether the fault is with the circuit to the starter motor, or
with the starter motor itself, connect the starter motor directly to the
battery with the 30 terminal and 50 terminal leads. If the starter
motor turns, then the fault is in the circuit. If it does not turn, then
the fault is in the motor.
