Hiya all,
I have a recently restored an 8032 that has been giving me sporadic problems with blowing fuses. When I first got it, it was completely dead. After cleaning it all up, replacing one of the rectifiers, some RAM, a burnt out trace and removing the line filter, it's now working well. Most of the time...
About once every 10 power-ons, it blows the fuse. Only on power-up though, never once its running. When running normally I can measure that it's drawing around 0.4 amps at 240 volts, around 60 watts, which is well under the rated fuse value of 0.8 amps. For most of the problems I can think of I would expect it to always blow (shorts on the board, dried out electrolytic caps, failed transformer) but once this one is running, it's rock solid. I also know it's not the monitor, as it was doing the same when the monitor was disconnected. I am a bit stumped as to what could be causing the issue.
Any suggestions chaps?
