im in brandon l322 and p38 and an empty bank account

the fat orange wire connects to the thin black/purple wire there is a green wire & a black wire i know there is nothing wrong with the motor as it runs with diagnostics or by bridging terminals at relay 20

i have removed relay under seat & this throws up a fault so guessing its ok as for orange wire i was under the impression that this goes to thermal cut out & green wire runs to compressor i could be wrong as i say electrics are a mystery to me

checked fuse 29 looked good but replaced it, no change also orange wire to compressor goes live with engine running, should it?

long day spent working on rangey & achieved nothing electrics are a dark art to me but i definately have no power to pressure switch or at pin 13 on ecu the air is low now & switch has changed state where do i find the power supply? as i have no idea rave is no help either

lol ok no worries i dont have pressure gauges etc think i might put it back to springs need to many tools & money to fix this thanks all for your help

hi there thanks for the reply i ran the compressor manually for 10 mins till it reached full height once unplugged the valve block did all its clicking putting car to ride height

hi guys just about recovered from flu so back to repairing the rangy lol i`ve just test the pressure switch for continuity there is no change of state from empty of air to full pressure this is the green switch fitted into the valve block i believe i had just replaced this with a brand new one...

hi thanks for the replies dont feel quite so alone now lol i tested the thermo switch by shaving back a small section of the orange wire just as in the link & ground it to earth it didnt run either but to be on the safe side i fitted a brand new one i also fitted a brand new pressure switch (the...

thanks all for your help looks like a trip to a specialist if that doesnt cure it then it back to crappy springs hey ho

i have a choice of 2 lol & tried both still the same

thanks but i tried that yesterday too completley drained system still no compressor i would just live with this but i tow a 3 ton compressor & after 10 miles she throws a fault & sits on the bump stops

ive swapped relay 20 for a known good one if i remove relay bridge terminals to run pump suspension will go to max height when i replace relay it drops to correct level

the dash switch is connected & lit i have tried another one it all seems to work as it should just no compressor i originaly bought my rangey on springs & recently bought another on air for spares so i changed everything over the only things missing on mine were the air bags & pump but over the...

the pump will only run if i use rsw software or bridge relay terminals there is good idle on software too

hi all yes engine is running suspension works perfectly on switches stays at correct heights but will not run compressor automatically there are no faults on rsw software

hi all just about had enough i`ve retro fitted eas to my 97 p38 4.6 but i cannot get the pump to run automatically i`ve checked the thermo switch even replaced it changed relay changed ecu but no joy it will run with reset tool & by bridging relay terminals there are no faults showing &...
