Background: HiLo, a 26' 2000 model, was left up with the power button in the mode to control the raise / lowering. The trailer lowered itself slowly in about 3 days. Battery quite dead. New battery not effective at raising the unit. No sound at all. No motor engaged. Can't get to fuses because unit is down. Can't raise because pump handle on hydrolic unit is broken. Any ideas helpful. Thanks. Joe
