water pump electrical help

[roguepra]

2016 27hfs, when the pump comes on while running on Batteries the whole trailer shuts off and on as if a circuit breaker is blowing and resetting. is there a main breaker to check for this? i thought i would check that first before looking into a faulty pump....any ideas??? thanks steve

Check battery voltage and battery ground wire. A loose or dirty connection can cause a voltage drop.

Battery could also be bad or badly discharged.

Do you have the problem when on shore power?

Roguepra...you haven't given enough info. Does it do it on both battery and shore?
