Hatch trouble on 1988 Stinger 375

[pbuckwalter]

I'm the proud new owner of a great 1988 Chris Craft Stinger 375.  Love the boat......especially when I can make it out on the water.  My hatch just stopped working over the weekend and I can't get into the engine compartment.  The previous owner has hot wires to jump that hatch but its still not powering up.  When I flick the hatch switch I get  a slight buzz followed by 3 beeps.  Does anyone have any suggestions? Could it be a fuse (if there are any) or a switch?

Thanks for your help in advance.

My boat (310 excalibur) has an hydrolic pump to open the engine compartiment. Behind my rear seats is a round plastic cover, when open
it is just in front of the lower attachement of this hydrolic pump. So you can unlock the base attachment to the hull of the hydrolic opening pump, and open the engine compartiment manually
