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.

Hey Karl,

Allen-Bradley makes a nice timer. They can be set up in many modes.
They would handle the pump relay (not the pump direct). I use one of
these in a similar manner to protect my air compresser so it doesn't
run too long or too often.
