While at WOT roughly 5700rpms I had my engine cut out and lose power. Instinct was to let up, when I tried to get back in the gas it wouldn't spin up right. I looked down and the oil light was on so I immediately killed the switch(was still on a plane). After stopping I could turn the key on and the oil light stays on continuous. Never did the alarm sound. I trolled out and loaded on the trailer went immediately to a mechanic. He done just a quick check and it is holding good compression and four cylinders are firing in neutral. Both tanks full of oil. After getting it home I drained the oil tank on the side of the motor and checked the switch with a voltmeter. Switch is working and buzzer sounds with reservoir empty. ( with it empty it would not automatically pump oil from one tank to the other, but the manual switch works fine). I am now out of ideas. Any thoughts opinions advice would be appreciated. Thanks Joel.
