blown diode fix -and
Yes Dr Bean is right, and I have only seen them go to "closed" - high current and no indiction of function. But if it were to fail open one could put a new diode outside the steel. My fix is to do exactly that. The how is a die grinder cut in just the right spot and the burnt diode can be picked out. I tried cutting the whole pump -actually to try rewind the coil -(I know now that was just dumb, us mechanical engineers are sometimes slow that way). But I learned where the diode was and also learned that cutting the steel breaks the magnetic path and the pump will barely work afterwards. I still use it as a test unit tho.
Dr. Bean: yes I too have a job. I hope to change to a priviate business but it wouldn't be cycle stuff - not that that wouldn't be fun.
