Pole Position Power Supply Blowing Fuse-Help Needed
So my boss bought a Pole Position running a PPII board for the office. It was working fine for a few weeks, but then it conked out. More specifically, the monitor is still working (has a re-capped G07 chassis) as is the fan, but the PCB was getting no power. After packing this up in the car and bringing it home, I got a better look at the PS. I replaced all of the fuses, but noted that one of the fuses had been replaced by some weird fuse hack:
The two fuses seem to be wired in parallel and replaced a 250V 7Amp fuse, the holder for which was all burned out. I can't tell what type of fuses are in that little hack board. After removing the PS, I noticed that underneath, the wire coming from that hack board was completely burned and broken. I replaced and resoldered the burned wire, and cut the "extra" fuse out of the hack board and replaced one of the fuses with a 250V 7amp...trying to go back to what was "originally" there. When I plugged everything back in, I was excited to see the PCB LED light up again and was greeted by brief PP sounds...but my joy was short-lived as it only lasted a few seconds as the new fuse I just put in was blown.
Are there any known common issues with power supplies in these? I know that sometimes the PCBs can be flaky, but is there something that typically blows fuses? Thanks guys!
