emergency hand pump opertions

[cessnadriver]

Herb. I fired up the front engine (with the hyd. pump) and cycled the landing gear lever from Down-neutral to full down, and nothing. When in the down position I do hear the hyd. pump under load. I checked the schematic for the landing gear system (hydraulic and electrical) and I see that the only way the solenoid gets electric power is with all three of the down lock micro switches are closed. I check and verified that the solenoid was getting electric power? Since the jacks and hyd. mule are located at a distant airport I was going to see if I can depressurize the the gear doors actuators and manually close them?? Thoughts?
Many thanks, BILLS

There are no switches on the doors so one of the down lock switches is not closing. Check with an OHM meter each switch, one on each of the main gear and one on the nose. If those check ok then you have a bad wire. The wires are in series and must make the circuit. Visually check each wire connection and terminal end.
