Have a question not sure if it should be here or in elec. Level up has started tripping breaker when retracting jacks. I have the level up on it's own circuit w/70a manual reset breaker. Checked with amp meter 55/60a when extending 65/70a when retracting spikes to 100a at end of cycle in auto retract so far working fine in auto level. This has just started. Has anyone experienced anything similar if so what was done. Is there any way to test motor and pump separately are they only able to be replaced as a unit?
