  1. I wonder if a different rating of resistors would work...? Risky I know. But we all agree it's broken right? In one set of pictures in this thread the resistor color code looks orange to me on my mac(note I lost my color vision years ago to an undiscovered tumor crushing the optic nerves, but it was treated a while back and now I have fantastic color vision, but am still learning to associate names with colors) -- anyway, orange would be .33ohm. In another picture is almost looks like there is red barred resistors (.22 ohm) AND ones with orange bars (.33 ohm). I am waiting on parts from mouser.com and will take a look when I get the unit out. Often the underlying color of a resistor will make the bars look different then the intended color. The only way to know for sure is to test a known-good resistor on a ohm meter. Question: The resistors may act as fuses to protect the MOSFET rather than the other way around (or both?). If they are too low resistance that could blow the MOSFET vs the MOSFET blowing the resistors...? I have several EEng friends; I will chat with them as soon as I get my unit opened up. I had a similar thing happen on my Samsung LCD TV. Factory resistor parts were too low resistance and the tolerance top poor. They blew and took out a MOSFET used to turn on the TV. An EEng online figured out the right resistor rating needed (more resistance, higher wattage too). I replaced the resistors and MOSFET on the TV and it's been years and it still works fine. Samsung would not cover the repairs even under warranty! I also had a similar thing happen on a Magtag washing machine. Poor quality resistors blew a MOSFET that operates the wax-motor driven door latch. Again, I found a fix involving narrower tolerance resistors with a slightly different resistance rating and replaced the blown MOSFET. Worked great ever since. So maybe it's a similar situation here? I'll let you know what I find. Scott
  2. [bTW: I think Markthis is referring to resistors not condensers) Thanks everyone for contributing! I have the same thing happening on my 2004 Touareg V10 TDI. Buttons on door handles stopped working and the automatic open (pull driver door handle twice stopped working, and the rear lid window stop working, then magically for a few days worked, then never again). As of this writing The Mouser parts are still available (April 25th 2016). Interesting enough. The battery under the front seat (accessory battery) keeps getting massively drained and eventually fails and it started happening after the kessy unit failed... I will do the repair to kessy as indicated -- also I replaced the front and rear batteries. I have to replace the front battery about once a year, until I read about failures of the kessy(!), hopefully this will fix it. I will likely have the local printed board assembly service in Bellevue Washington USA to the soldering PCA - Printed Circuit Assembly for $50). The alternator been acting up as the front battery went dead (lost a cell), eventually brining the 'Egg to a stop, and I replaced the battery and now the alternator it won't charge at all, before replacement it would output 14V, but started going whacky the worse the front battery got. All seeming to be caused originally by the Kessy. Is the source of the problem in the Kessy unit due to water ingress? Scott
