Aerator pump blowing fuses

[Wish-I-Were-Fishn]

I have a Rule aerator pump that keeps blowing fuses. As soon as I put in a new one, and turn on the switch, it pops the fuse.

Any ideas on where to start looking for the problem?

Cracked insulation, shorting out, make sure the wires are + to + and - to -. I was a dummy once, put them on wrong, and three dollars in fuses later I figured it out.

I agree the suspect sounds to be a wiring issue. One might also check the impeller on the pump as something could have it stuck in place and it wont turn.

I wondered about the impeller. If it is stuck, will that cause the fuse to blow?

It might not blow that fast unless motor is burned and shorted out, in which case all the suggestions above apply.

Fuss is 2 amp, but I can't find one anywhere. My dealer says to use a 5 amp because if anything is/gets caught in the pump, it will pop the fuse. If it pops with a 5 amp then I have problem.

Watch out with 5A fuse Rules suggest 2A Do you have the 3 wire one? if so the brown/white tracer wire is for a switch the other two are ground Black and Brown POS,they are for the float.The brown/white tracer is not needed unless you'd like a off/on switch. I get my 2-3 amp fuses at Kmart or Menards

Also its white top blue base/strainer there are two tabs between the two to release motor from strainer,pop it off and turn the impeller by hand.then try it disconnected from strainer,maybe even cut the wires and go direct to batt. see if it works.
