Hey all, I have the 6 pump system on my Max, and today I went out to adjust the timers. The rear bags filled in 4.5 minutes, and emptied in 5. This is one at a time engine idle.

The center bag was taking over 6 minutes and the pump(s) auto shut off. This is when I opened the round access in the floor, turned the pump(s) on again and realized only one pump is working. No matter whether filling or emptying, only one pump is powering up.

I got out my multimeter and I went ahead and disconnected the non working pump at the quick disconnect in the wiring and tested the incoming power...nada. I put that back together and checked the working pump power and it properly registered 14.xx which should be good.

Is there some in line fuse or circuit breaker I need to replace/reset?

The manual shows only one circuit breaker for all ballasts, I will go have a look at that now.

I am also going to try the (bad) pump when plugged into the (good) pumps wiring and vice versa.
