For the inspection i had to adjust the parking brake and to not have to take the cable loose again I installed the battery box. In the picture you can see the parking brake cable goes thru the rear in the battery box.
I also wanted to get the airco working and started rewiring. Decided to use the original relay board and mount it to the skirt condensor. Doing so shortens the wiring. I also wanted to restore the original Ford switches and wiring as good possible.
The original Ford high and low pressure switches were removed. After I bypassed both original high and low pressure connectors the original Airco clutch connector worked again.
Took some time to understand the wires that went to the evaporator.
two wires for a low pressure switch. One neutral, Three wires for low medium high speed and one not connected.
Extended the low power wiring to the skirt fan motor relay. From that relay i took the fan power via the high pressure switch at the skirt condenser and the low pressure switch at the rear evaporator ( both closed under normal operation condition) to the airco compressor clutch.
I measured the current thru the skirt fan motors --- 15 Amp total at 13 volts.
Mounted the rear evaporator fan switch at the kids dinette.
It cooled pretty darn good. At idle the battery voltage remained at 14.3 Volt with front airco fan at max and rear airco fan at medium.
The current thru the rear evaporator fan at medium speed was 9 Amp.
