My livewell will not pump in water, everything else works with it but it doesn’t pull in water from the lake. I tested the fuses and found the bad one. I tried 2 new fuses and blew them as I flipped the switch. Well then I blew water into the back and front of the intake and then took off the pump and blew water in the case that holds it, put a new fuse in and it work for 10 seconds longer than it has since it broke. Then it blew but there was more sparks this time any suggestions or ideas?

You have a short.  Where were the sparks coming from?

Top left of fuse box. Number 5 fuse

It's sparking at the fuse?

The fuse box, top left fuse it sparked for like 2 seconds though

So, you have a short, either in the pump itself, or the wiring to the pump.  I'd disconnect the pump, and check it separately, but be careful!

disconnect one of the wires where the pump motor is spliced in.  Replace the fuse and see if it blows.  If it blows, you have a shorted wire and need to find the short or just pull a new wire (mouse may have made lunch out of that one).

If the fuse does not blow after disconnecting one wire at the pump, then replace the pump.  Something may just have the impeller jammed but after blowing several fuses, it has probably wiped out the motor anyway, so I would just replace it.

When you see a clear  fuse flash like that and it's all black and vaporized, that means something is shorted to a near dead short.  When it just melts the center section and is still clear, that shows it was just over loaded.

So the yellow pump works well I’m assuming it just circaltes the water. It turns on when I flip recirculated switch. The aerator switch is what doesn’t work. Does that still run off that Mayfair pump?

Lesson learned many years ago was if a fuse or breaker is tripping, do not keep replacing it if they keep breaking. They are trying to tell you something, which is usually "keep doing that and there will be greater damage." Better off stepping back and start poking around with a meter for shorts, do visual inspections, etc. (but disconnect the power source first). You probably already know but don't replace the fuse with one of a higher rating than what the spec calls for; it only encourages damage/fire.

 

If there's not an obvious short somewhere, I wonder if the pump impeller is seized or somehow blocked from turning. That might cause wires to heat and clear the fuse. 

 

Yeah I’m done throwing away fuses lol. I looked around everything seems fine with wires which is what is weird the Mayfair pump works great when I flip the recirculated switch but not at all even the switch doesn’t light up when I flip up the aerator switch. It does with a new fuse but then blows.
