So new IRL540 came today... soldered in place and same as before.... picks up ball but does not release it untill most probably the fuse blows as it has done so now...
So with Beakys LED test everything i thought was ok up untill magnet driver board as led switched on and off at correct intervals.... so is it safe to say problem is on magnet
driver board? What on the driver board would make the IRL540 lock to on position?

Lucky i orded 3x IRL540's this time
