power out terminal when engine is running, pressure
switch is potentially faulty. Remove switch and install
a pressure test gauge and start engine. Consult
troubleshooting section of this manual for oil
pressure testing instructions. If adequate pressure is
found, replace pressure switch and confi rm
operation/voltage readings.
