Upgrade water pump wiring?
Has anyone measured the voltage at their water pump while it's operating? I'm seeing ~6 amp load and about 10 volts with the pump running wide open (multiple taps opened.) Battery voltage is at ...

Is the voltage 13.2 at the pump when it's off?
I seems to vary, there must be some other load on the circuit that's not static. Right now, it is 12.7. Earlier it was 13.2.
There is a strip of LED lights in my basement that is also on this circuit, they are turned off with a mechanical switch. The CO/LP detector is on this circuit, it is operating.

Voltage readings before and after the pump's pressure switch? At the fuse box with pump running.....?
Indeed you need to determine WHERE the voltage drop is occurring.
Good ideas. I will measure the voltage at the fuse itself when I open that area up to check the wire nuts.
I'll see if I can reach the nuts for the pressure switch well enough to get the meter probe in there, they're tucked back behind the pump.
