when the ignition switch is turned to START. The solenoid protects the ignition
switch from the high current drawn by the starter motor.

terminals 1 and 2 are open (no continuity).
3. Apply 12 volts (DC) to terminal 3 and ground terminal 4. Terminals 1 and 2
should now be closed (continuity).

As part of the safety interlock system, the PTO switch will prevent the engine

from grounding through the hour meter.
