Blowing water pump fuse

I just got my water system more or less functional and now it is blowing fuses. I am assuming the water pump has a dedicated fuse? I have not had a chance to unhook the pump and plug in a fuse yet to see if it blows with the pump out of the circuit. I expect the pump motor might need some R&R or maybe there is some trash stuck in it. I don't think the pump is original. The pump would not be a big deal but I am afraid that if I hook to city water that I am going to have lots of leaks. The PO has a hodge podge of PEX with hose clamps here and there etc. I may or may not have time to fix these problems at least the ones I can see. I am sure there are other plumbing rigs I can't see.

Hose clamps do not work well with PEX (personal experience). PEX is too hard. I stripped alligator clamps trying to keep PEX from leaking.

As to the blown fuse. unplug the pump and make sure that the fuse does not blow with the pump out of the circuit. Not knowing the age of your pump, I can't recommend the next steps.

Yeah hose clamps are not cool. The pump looks pretty new. It still has paint on it. My rear bedroom lights are working now. I am one fuse from getting everything working accept one light above the sink. I will check for shorts and then pull the pump out and take it apart.

Well looks like a short. I wonder where it could be shorted? I unhooked both pump leads and it still blew a fuse.
