Tiara 35' 1998 twin Cummins -- Engine Hatch Actuator jammed

[plagasse]

Hi -- I have a 1998 tiara 35 express that has two actuators that lift the big hatch off the engine compartment for access.  Apparently one is now jammed or not working -- only one Port side attempts to lift and only goes up about 2"  I can use the smaller hatch to get to the engine space, does anyone know how to disconnect the starboard actuator or the lock that apparently is not firing to let it open on that side?  A nice parts diagram of the attachments would be helpful or basically anything that allows me to see how to get the big hatch open with just one actuator so I can fix the broken one.  I can be reached at plags@comcast.net or here
