Welcome to CSR.
You're more likely to get a response if you specify which model EC you have...
Is this a general question about the pump wiring or something that would be specific to your model boat?

It is a 93 250 express cruiser, I am looking for the diagram for this boat, My front pump stopped working, no power.
I started checking it out and found the - was hot so I need
to find the short. thanks for the help, I'm new to this!!

Do you have a three-way switch for the bilge pump at the helm (on-off-auto)?
If so, you'll have two hot leads running to the pump- one that goes directly to the pump (on) and the other that provides power to the float switch (auto).
I would check the connections at the pump wiring. If they weren't done properly- like non-waterproof connectors all taped together and lying in the water- it's the first place I'd look for a short. You should use heat-shrink connectors, and fasten the connections somewhere high & dry above the pump where they won't be lying in the water.

Let me ask you somthing, My boat has three pumps two have a float switch one does not, I have one switch on dash three pole power,load,ground. The switch is just on/off.
Now the float switches do not go directly to the pumps they must tie in somewhere else??? thats were I think my short is because I all my pumps quit all at once. With that being said I need to move on and fix this thing, My ? is this the two pumps in the rear bilge I am replacing both pumps putting
a float switch on one should/can I use the power wire coming from the switch for both pumps??
Thanks for your time

No problem using one float switch to power both pumps PROVIDED the switch is rated to handle the amperage of both pumps together.
Most float switches are 20 amp- so provided both pumps don't exceed that you're good to go. Be sure the wiring from the power source is adequately sized as well.
