No Green Light on gear, after sitting for a week

[Skymaster337B]

I Installed the actuator back into the airplane today. Not easy, unless you have 3 extra joins between your elbow and wrist. Doing it the way the book said DOES NOT WORK. The way I finally had to install it was: install the downlock hook by itself onto the strut. Then, screw the actuator piston into the downlock hook. Finally, install the actuator forward end into its slot.
