There isn't even much dust inside (not that there are vents the dust could get sucked in). > Also check the 7815.

It's getting warm, and something is definitely drawing excess current. Thing is, it wasn't doing that until I started probing around. Could be coincidence, but I'm not convinced. > Also, if anything else seems to be getting hot it could be worth a closer= look, I can't seem to find much else getting warm at this point. > A schematic would be of great assistance, but they can be hard to find. > > hope this helps. A schematic would be a lifesaver at this point. Seems unlikely though. I'll give it another couple of stabs before I give up, but I really feel like I'm working in the dark on this one. Thanks!
