We had a power outage. Afterwards my Pentair power center when powered on instantly blows the 10 amp fuse. It does so with or without the cell attached. I assume the pcb is bad. Any help would be greatly appreciated.

If I disconnect the two red leads coming from the voltage transformer, the fuse does not blow. Once the two red leads are reconnected, the fuse blows. I assume this would mean my voltage regulator is bad. I show that as part number 520722. Can anyone chime in and let me know if I am on the correct path, or am I looking at just replacing the entire unit?

Gotcha. I did find a complete unit for $312 shipped, which I may do, just to be certain. Then I would have a backup transformer and enclosure. I will let you guys know the results either way. Thanks for the input.

It is your decision to get a new unit, but the Board is almost certainly your problem. Transformers are very rugged devices, and seldom fail. If it were me, I would just get a new board for half the price of a new unit. Just my opinion.

Can you point to where this fuse is located for you? I cannot find where mine is located for the Pentair IC40
