1985 Auto sleeper on demand water pump

[Sir Brixalot]

It's not running at all. I've got the electrical feed going to the motor and the red wire that comes out of the bottom of the pump connected to the pressure switch. It tat correct? Will check that electricity is coming through one meter batteries are charged,

there are two wires entering the pressure switch.

You can bypass the switch and see if the pump runs.
Just temporarily connect the wires together with a short piece of wire.
The pressure switch is often the culprit.
They ae generally not serviceable either.
