Starter will not engage
in General Tech Discussion
10 years ago
Head scratcher this one, at least for me. Recently my 912ULS-equipped aircraft has developed a bizarre problem. First flight of any given day the starter engages and the engine fires normally. Subsequent flights however and the starter simply refuses to engage. Well, not immediately at least. After 5-10 minutes of swearing, panel bashing and button punching, the starter suddenly engages and the engine starts normally. I have a push button starter so immediately suspected it had gone bad, but continuity tests show both it and the lead to the starter relay solenoid are good. What is changing between first start and later unsuccessful attempts, except for the obvious heat buildup. And are solenoids susceptible to heat buildup? And if so why didn't this behavior occur in summer? Any and all ideas welcomed... :pinch:
