Livewell pump problems

[huntingislife]

I am looking for some help here. I am hooking up my livewell pump and keep blowing the breaker. The pump had been disconnected by the previous owner and I am reconnecting it. If I take the pump up to the console(with about 6 inch wire leads) and run it using the breaker and the same ground location as before I have no problems. But when I hook it up in the back with one wire going to the same ground and one wire going to the breaker, it blows the breaker. I just ran the wire so it shouldnt be damaged. Could it be the the 10 feet of wire is causing a larger load and blowing the breaker? I also swapped breakers with the bilge and it would blow that one too. I checked the impeller and it isnt clogged either. Somebody help please

Just a thought,try a larger gauge wire going to your breaker. To test this theory,try and double up the wire going to your breaker & see if blows again. If it doesn't,run a permanent single larger gauge wire.

Its almost certainly too small of a wire. The voltage drop in the wire you are using is making the motor work harder and likely is the cause of the blown breaker.

Well I will have to try larger wire. Hmmm, I used the recommended size. Thanks for the help.

You probably have a short to ground on your power wire somewhere between the breaker and the location of your pump. Disconnect the power wire at the fuse/breaker and at the pump, and measure the resistance between one end of the wire and ground. It should be an open circuit.

If it is not, I would replace that section of wire.

From your post it sounds like your pump only has 6 inch leads and you are splicing wire to make it go to your rear battery. If so remove the splices and test the voltage. Probably what was mentioned before as being a short. The other thing it could be is if you have a 24 volt system on your boat you might be hooked up to the wrong part for your postive voltage.

Thanks guys, I got it working.
