Dash A/C Wiring diagram

[ronmarabito2002]

Anyone out there have a wiring diagram for a 90's series Wanderlodge dash A/C
system.

Looking for voltage drop between relay in upper left control center over the
driver back to the clutch on the compressor.

Currently have 11.8 volts at relay and 8.6 volts at the clutch.

If I apply 12 volts to clutch, it will pull in and hold at the 8.6 volts, but
will not pull in with the 8.6 volts.
