Reconnecting the three wires you must connect blue to A, orange to B, and
yellow to C.
If you do have a 6 volt pulse voltage out and the compressor does not run you
have a defective compressor.
For additional wiring diagrams see pages 21/22
For controller pin out table see page 23
J. Condenser Fan Motor Testing: First do a visual inspection of all blower
parts.
For condenser fan location see Freightliner ParkSmart documents.
Reconnect any wires or plugs you might have disconnected when removing the
cover. Turn the Parked Unit on, if you do not have 12 volt at the fan, check
fuse F5 And relay LS4. If you have 12 VOLT main power, check for the signal
voltage from pin C 7 (white wire). You should have zero voltage with unit off
and 1.6 to 2.6 volts unit on. If all voltages are correct, reconnect the plug. If the
fan does not run, it is defective, and needs to be replaced
Using a DC ammeter you can check the amperage draw of the blower. Normal
amps approx. 9.5 max.
Caution: If attempting to connect blower to an outside power source,
internal electronic components are sensitive to arcing or reverse polarity!
Damage will occur!!
