Airator blowing fuses

[Northlander]

Checked connections and power and thats fine. Im assuming the pump is getting hot then blowing the fuse? Works ok in the garage but after about 2 minutes in the water it blows the fuses again. Its a Johnson with the Mickey Mouse ears so I think just getting the new cartridge is in order?

That funny cause I just bought one of those pumps because the Mayfair that I have now will blow the fuse but will work when I replace the fuse and the next time I go to use the livewell it will be blown. I like the way the Johnson is replaceable with out a complete rewire job.

You verified there's no gravel stuck in the impeller?

If you've checked that, and the power connections then it's time for a new one.

Changed both my Mayfair, (Johnson) pumps this spring. Both went bad over the winter. One was froze up, and I got the other going, but shortly failed aferwards. Easy to replace though. Junky....

Ya I cleaned/washed everything out and it works fine in my hand in the garage but as soon as it runs a while pumping water the thing pops a fuse. Im assuming its heating up under pressure.

I went down and got a 1000 gph cartridge to replace the old 1000gph on my bilge and a 750 gph to replace the 500 on my live well one. Should be golden now. As long as thats all it is. I couldnt believe the replacement cartdidges were only $20 a piece at GM.

Here is a thought for you. I have been having the same problem in my lund pro v. there are 2 livewells on 2 different fuses. Back livewell works but when i turn front on it blows both fuses. So I have been looking at why this is happening. I think it is the timer. Both livewells are connected to a timer. This is the only thing that is connected to both of them.

They're typically connected to different timer modules though...

It could be a power short at the switch (since they are very close to each other)...

i dont understand why mfg do not wire things through a relay so there is no load on switches and timers. also why they do not break the ground rather than power so you do not have a spark or surge to the electronics. oh well old school worked but the new way seems to make things last longer

[kevfish1]

mine just has one. It is about the size of a film canister. Located behind all the switches im my pro V

Same on my Explorer.
