gimp19 Posted April 29, 2004 Report Share Posted April 29, 2004 I got my A/C converted to 134a 2 years ago it worked for a year, now it needs a charge. I bought one of those kits with a can, hose and gauge. Problem is it barley takes any "freon" to get the gauge reading fully charged, the reason for that is I cant get the compressor to kick on and the instructions say it must be running to charge. Is there any way to jump it? Quote Link to comment Share on other sites More sharing options...
jeremy Posted April 29, 2004 Report Share Posted April 29, 2004 if you compressor isn't running you have bigger issues than a basic recharge.... Quote Link to comment Share on other sites More sharing options...
gimp19 Posted April 29, 2004 Author Report Share Posted April 29, 2004 I've heard if the charge gets to low the compressor wont run Quote Link to comment Share on other sites More sharing options...

Whiskey River Posted April 29, 2004 Report Share Posted April 29, 2004 I've heard if the charge gets to low the compressor wont run That is correct, if the static pressure is below 35 psi (I think that is the pressure), then the compressor will not kick on. Easiest way to force the compressor to run is to remove the relay and short the power leads with a 10 or 12 gauge wire. If the compressor starts knocking or grinding, stop everything and take it to a shop, compressors are expensive when compared to a couple ounces of POE oil.

gimp19 Posted April 30, 2004 Author Report Share Posted April 30, 2004 Theres like 5 leads on there witch ones do I connect? Quote Link to comment Share on other sites More sharing options...
Whiskey River Posted April 30, 2004 Report Share Posted April 30, 2004 If you look at the side of the relay, there is a small diagram. There should be 85, 86 87, 87A, and 30. If you short, 87 and 30, that should force the compressor clutch to engage OR attach a small wire to 86, on the relay, and then ground the other end of that wire. That will force the relay to close, engaging the clutch. Quote Link to comment Share on other sites More sharing options...
Slade901 Posted April 30, 2004 Report Share Posted April 30, 2004 Make sure you set the AC to Max/High setting and shake the can thorougly. Quote Link to comment Share on other sites More sharing options...
