I did add water to the batteries yesterday and must have hit the red plunger.
Glad you found the tripped circuit breaker.
Now you do know you shouldn't use the hydralic pump unless you are hooked up to shore power or positive you have 100% fully charged batteries.
The tripped breaker means that you has high amperage at the pump motor which is the only reason for the CB will trip. Low voltage
