This shows that you have +12v at the lead going to the compressor. this engages the clutch that takes drive from the engine to spin the compressor that operates the pistons in the air compressor that compresses the gas (the knee bone connects to the leg bone la la la) Shows that it works but make sure you put the right amount of oil in the compressor. Get the air-con person to measure out the oil and fill the compressor. If you are using RS24 gas you need mineral oil. If you have everything in bits use the o-rings that are R134a compatible incase you change your mind about changing to this gas. I'm not sure how successful this is as the R134a gas requires more force to move roung and will put extra strain on the compressor. Maybe more feedback from other 'D' owners how succcessful thier conversions have been. Specs are in the Delorean manual. Good luck, Nick.

Thanks to Ken Koncelik and his simplified instructions I got the evaporator core out in under an hour. Now just have to wait for the new one to arrive and 'pop' it back in, hope that's as easy. While I'm waiting I put a few other bits together, Condenser is now hung on the radiator, and connected to the compressor,and also now the pipe work and switches are in place over to the accumulator. So hopefully it is now just put in the evaporator and accumulator and have it leak tested and gassed. Please don't shoot me down for this, but I just had to check what was happening with the system so I fired up the car and turned the mode switch to cool and jumped the low pressure switch. What did I get, well the main pipe that connects to the accumulator and runs back to the compressor was sucking like mad....... and the pipe coming over the accumulator from the condenser was blowing well....... Is this a good sign???? Cheers Paul #6463 www.paul.salsbury.btinternet.co.uk [Non-text portions of this message have been removed] Yahoo!
