last nite wifey and i flew to pittsburg, ks to have dinner at "chicken mary's"(of "food network" fame). when we were ready to depart rnwy 32 into the very cold, very black skys, i noticed that my oil pressure guage was in the high yellow zone and when i ran up the engine it moved to the red. after pondering this, i toggled the landing light switch off, and the guage returned to normal...on again and it read high.
i think that the oil pump is mechanical...am i right? is this aberant reading with the light on a problem?
thanks for any advice.
p.s. this is a wonderfully friendly and accomodating fbo and is a fun little stop for food and fuel if you're in the area. pittsburg is also the home of "anywhere map" products.
