Subject: Re: A/C Compressor Trouble by Matatk on 2012/8/11 20:28:05 Bob - what Joel said. You need to use a set of gauges when you do the vacuum. One to the high side, one to the low side, the pump in the middle. Once you vacuum it down to 29, close the connection in the middle and turn off the pump. Let it sit for at least 30 mins and see if the gauge moves. Once the a/c is running, the pressure inside the line will get over 400 psi before the high pressure cut out switch goes off. An interesting thing with my conversion - I pinched an o-ring on the compressor manifold. Held vacuum perfectly. But after pressurizing it, began leaking and pushing dye out. Replaced that and no more problems. Also make sure your pump connection / high and low connections are good. Sometimes those quick adapters aren't screwed on enough and leak there. If you can't get a good vacuum, you might consider taking it to a shop that has the actual machine. Some shops have recharge specials for like $59 or something...well worth it in my opinion. It's cheaper than buying a good set of gauges and you will get the correct vacuum and refrigerant fill. Matthew |
