Quoted from zhu808:Thank you very much for this explanation. I did read extensively through the l.v. reset section for WPC systems on PinWiki about all of the things you mentioned.
I'll be doing some probing soon. Assuming the 12V circuit reads low, is there any way to bring it back up within parameters without getting rid of the mods, or is this always going to be the case? So, since the mods run off of the 12V circuit, the l.v. reset won't be triggered because it runs off of the 5V circuit (assuming it doesn't drop below 4.7V)?
Fix the 12v circuit. Usually the cap is the culprit and needs replacement. Hopefully it hasnt leaked and taken out a bunch of components.
