Hi Bob, Marshall has the post with more technical info, I have it at home. I used a pack that measured 82kohm. I'm getting as low as 37-38°F (3.5-4.0°C), which is ok with me. Something more like 90k might be a little safer. Mercedes says temps should not go below 5°C (41°F) but IMO that's a little overly cautious, especially in a dry climate.
Anyway, I got 1/2 watt (I think) resistors from Radio Shack, $1 for a pack of 5. They don't have the exact resistance we need, so I bought a pack of 1M ohm and also a pack of 100k ohm resistors to build the desired pack: 91kohm = one 100k, plus one 1M 82kohm = one 100k, plus two 1M I just twisted the leads together and soldered them into the leads at the male plug connector. It's kind of a pain but not that hard. I took a photo of the solder job with the three resistors, it's not pretty but it works. I'll post it to my website eventually. :-) Dave M. > ------------------------------ > Date: Thu, 11 Aug 2005 06:24:27 -0400 > From: Bob DuPuy <[EMAIL PROTECTED]> > Subject: Re: [MBZ] W124 A/C question - UPDATE! > > Hey Dave, > Thanks to you and Marshall for pointing this out!
