Intermittently, my master solenoid seems to "stick".
Turn on the Master switch - can hear the solenoid activate.
Turn the key - engine turns over to a compression stroke and stops.
No further power to the starter when the key is turned. No power to the avionics or anything else.
It appears that the solenoid is de-activated.
Master switch left ON and in about ten seconds, I can hear the solenoid activate again.
Engine will usually start normally at this point.
I have a feeling that the starter pulls enough current that the voltage to the solenoid drops to the point where it "opens". Then, as the voltage rises after a few seconds the solenoid "closes" again.
It looks to me as if the solenoid is defective and needs to be replaced. I have another on order - should get it in about three or four weeks ( !!! ).
Thoughts?
