Electrical Problems

Thanks Dave:

On my P model the cb is labeled "oil dil , tach, oat". The tach and oat both work even with the cb popped so I think that only the oil dil is connected. I changed the cb just to eliminate that but no joy. I don't believe that I have oil dil on the plane. I have tried to trace the lone wire from the cb but cant ID it thru he firewall. It has to go to the aux pump and I am looking there now.

I have also jacked the a/c and believe the landing gear switch is faulty. Waiting for switch to arrive. That should fix the gear problem. We are gaining on it. Thanks for the post. Much appreciated.

Okay, so someone has gotten creative behind the panel. I would tend to disregard the breaker labeling in this case. The wire is going somewhere. You only have two and a half options for the popping breaker. There is either an excessive load to whatever it's hooked to now or there is an intermittent short. The half option is a bad breaker that trips all by itself. That is a much less common situation. You should also be on the lookout for something that was disconnected and the wire left dangling.
