in a bucketVBG I feel kind of dumb. The control box has motor
overloads. Only had the pump since '82 and didn't know that. At least
it was a cheap fix.

OK, the problem was short cycling. Air bladders out of air and pump
running 15 seconds to make pressure. I'd like to build a better mouse
trap. I'm thinking of a short cycle alarm. Get a timer relay that
trips when power is applied. If power drops before timer runs out,
apply power to buzzer. Should be just a few relays and wiring. But my
brain is pea size when it comes to EE logic. Can somebody draw this
up? Or, I'm open to another idea.

Install an air pressure sensor on the air side to alert you when the
pressure falls too low?

I could be wrong, but I don't think that would work - the pressure
stays the same, just not enough volume??
