C152 - Propeller goes off on Master only (with keys out)
Those familiar with C152 / Lycomings / the way the ignition starters are wired:
C152's propeller turns when the master switch is on (both halves - battery + aternator) but the ignition keys are out of the ignition lock (i.e. in none of the R, L, BOTH positions or START :-). I would suspect faulty / burnt ignition switch is the culprit. Is there any other potential reason? Does this happen often (as none of the people observing the fault have seen similar thing and they do have some experience) What would happen if the engine caught up and the ignition was firing into the running engine? (i would expect there would be heaps of out of place ingintions making the engine run uneven, am I right, wrong, is there anything else?)
Thank you guys!
