Voltage Morryde Zero Gravity Ramp
If you have a Zero Gravity Morryde Ramp that has a keyed entry with electronic actuators for unlocking your ramp, here is a note about the batteries and connection to House Power/Main Battery.
The unit comes equipped with a 9 volt battery by pass that is intended for dealer locations until the main battery is installed and has full charge at all times. Once the unit is sold, the dealer is suppose to disconnect the 9 volt battery bypass and connect to the pig tail that connects the power to the house power/main battery.
The pig tail and 9 volt batteries are located in the front under belly hatch to the left of the generator compartment against the back wall. At the top there will be a block cover which houses several wires with wire nuts and the pigtails. If your keyed entry does not operate, check to see if the bypass is hooked to main power, if not, then hook to main power or replace the two (2) 9 volt batteries...
If this does not work and your ramp still does not unlock, then replace the actuators.
