Air suspension pump testing.
DAVE39V8:
Can anyone tell me what the 3 wires to the classic air suspension pump are..?
Without looking I think they are green/orange/black???
I have just changed mine and want to test my old one by connecting it to the battery and dont want zap myself or something. :oops:
Dave :)

Not sure of the colours mate. I stripped down my 110 K miles compressor and although the piston seal was 'tatered the rest of it looked pretty good. The brushes were probably about a third worn. The piston seal was split and there was a yellow dust inside the pump chamber.
If you pull the motor apart it's a [!Expletive Deleted!] to get it back together again as the brushes pop out . I made a couple of hooks out of MIG wire to hold the brushes while I wiggled the motor end cap back on. Even so it took a while.

Black, earth, green motor IIRC, red temp sensor. For sure one of either green or red is thicker, this is the one you want.

thanks RRB least i can check my old one..the rangie is in being checked out at the mo..i changed the pump/compressor and they just phoned me to say it still not working and ECU showing no faults..
waiting for the them to try trace fault now..loadsa money :cry:
DAVE39V8:
Got Rangie back from ECU fault clearing....and.....the faults are cleared but the pump still not working..
Now,I have checked my old pump that I removed first,connecting green/black to battery and it worked..
So I did the same to the "second hand" pump in situ and that worked too(now I am puzzled).
I've had the pump on car running for a minute or two by connecting the wires straight to battery but it didnt seem to pump up the suspension.
How long can the pump be run like this only I dont want to run it too long and burn it out.. :?: :oops: :?:
Also what else could be wrong now :?: :?:
