Myers 1 HP Centefugal Pump not Starting after Electrical Failure

Hi there,

I have a 1 hp Myers pump for a shallow well used to
irrigate my 1/4 acre yard. It was working fine (i assume although I've
never had an irrigation system before) but one day we had an electrical
issue and now the Irritrol Rain Dial device is on and there is an
electrical sound (just like it used to make to turn the pump on) but the
pump itself is not kicking in.

Here is a quick detail on the electrical issue:

All of a sudden, a fuse in the breaker panel would not stay on. This fuse
controls the irrigation system, the garage door opener, a small mini
fridge on the back porch plugged into an outlet, and one other outlet in
the garage. A neighbor and myself reworked some of the wiring to
include re-cutting the wires and resetting them in the fuse. We also
replaced one of the outlets as the other was old and cracked. The home
was built in 1959 if that matters. This worked and everything operates -
except the irrigation pump.

The irrigation pump is a myers 1hp and the control is an irritrol rain dial unit. Both are housed in a
Suncast 6 ft x 3 ft hard plastic outdoor shed. The irrigation pump would
typically make an electrical hum, then kick on and sound like a
generator running. I assume that to be normal just because that's how
it's been the last 8 months since I've owned the house. Now however, the
electrical hum begins but the pump does not engage. Is that normal
after a power outage? The pump never sounded squeaky, never surged or
did anything out of the ordinary really. I don't want to replace the
pump and experience the same issue because of a power issue with the
house and I don't want to call an electrician out and it simply be a bad
pump. I may have to do both but want to avoid that if at all possible -
one income and a baby on the way!

Sorry if I clouded things with too much info, just want to be thorough. Thanks for any help.

Rain Dial to pump relay switch to pump?
If so, what relay switch?

Since you want to be around when the baby arrives, you should take very great care with this pump, as it might be running on dangerous 240 volt power that can be fatal to contact.

Is the pump on it's own circuit/breaker? Is it the garage breaker that keeps tripping?
