Mid-East Nebraska | Yes it will need 12 volts to disengage. It also has two brake switch's at the brake pedals for disengaging when you push on one brake in auto and when you are running at higher MPH and push on both brakes the mfwd will engage for braking on all four tires. Check to see you have 12 volts in the off position, if it has 12 volts then you will have to install a gauge to see if there is pressure to the mfwd clutch, if there is no pressure then most it's most likely the mfwd clutch valve. If it's not the valve then the piston on the mfwd clutch is leaking. | |
