I'm gutting all the power wiring and re-working everything. I can't sacrifice any more expensive electronics to shoot this gremlin.Reducing the power supply count from 5 to 2. (Granted, these are going to be massive power supplies to handle everything the sim throws at them.) One 12VDC/83 Amp supply, and a 5vdc/60-Amp supply. All power end-points will be fused, so if something shorts out again, just the device is affected and not everything else.Funny thing is, I should have known better....Turns out that using multiple supplies can have negative consequences, too numerous to list here.

How many are you using for your sim?All I know is 2 is not enough, it will heat everything up based whatever the most amps being used at one point is. Put one 8amp device and 6 more lower amp devices on a 15amp circuit, and the lower amp devices will get the heat up from the 8 amp device. You'll get shorting issues, burnouts, browning of both power supplies and surge protector strips.

Yes, I studied basic electronics along the way in high school and college, but I have never been motivated enough to delve deeply into the subject regarding my sim simply because I have not encountered the kinds of issues reported here (necessity is the mother of all learning). So bottom-line, I guess maybe I have been dumb lucky.But for whatever it is worth.....The current rendition of my sim is about a decade old now. It is a fully complete enclosed fixed-base 737 cockpit. It does not have the complexity of a motion platform, but does have the complexity of a multi-channel visual setup.I have 8 dedicated 20 amp circuits in the sim room. Those service 6 computers, 3 projectors, 10 monitors of various sorts, 5 converted cheap PC power supplies for the sim electronics (5V/12V), and some 24V transformers for lighting and other minor applications, etc. The sim electronics for the fully functional OH, MIP, and the converted motorized TQ are home wired, all else is pretty much plug-and-play. There is no wiring for converted real instrumentation other than the TQ. All electrical current into the sim is downstream from 1875W surge protectors, but none of the home wiring is fused (because to this point I have not been motivated enough to engineer that part of it). I make it a point to close the power at all the surge protectors when the sim is not in use, so there is no electrical service connections into the sim or computers when I am not there.So that is my report. Again, I am not smart enough about electronics to know if any of that provides any learning or valuable insight. I'm simply reporting what it is. I may just be dumb lucky since I have yet to have any electronic failures of any kind (other than some really stupid and obvious wiring mistakes that I made that fried a servo or two, and a headset module that failed for some unknown reason).
