but next day, it won't restart.

Well, first of all, you'll get better responses in the r.a.owning newsgroup.

Secondly, THREE new starters? Someone's got a thick skull.

Thirdly, in spite of the the "testing" of the batteries, the problem sure
sounds like a battery problem to me. With all that replacing of the
starter, did it occur to anyone to put a brand new battery in the plane? Or
to try starting with an auxiliary power supply?

If the battery does check out, then it seems to me you've got some more
testing to do:

* First of all, after the supposedly bad starter has been removed, has
it been tested? If the airplane is actually breaking starters, you'd
probably want to know that before putting more starters in the airplane.

* If the starter that was removed checks out okay after removal, and a
new battery doesn't help, then it seems to me that there is probably some
sort of electrical problem, and the messing around with the starter is
enough to wiggle something so that it works, for a little while. What that
could be, I don't know. What I do know is that whoever is working on this
airplane right now probably ought to hand the job over to someone qualified.
They obviously aren't.
