Pump lifts but will not gravity down.
\015 I have a 12 volt electric dump hoist with power up and gravity down, The pump will lift but not come down.\015
Either the ram is very new and tight not enough weight to bring it down oror the valve in the pump is not going across to let oil back into reservoir, usually need to power this across.
