Iceman,
I just bought a 92 SVX on Sunday. It had some electrical problems also.(dash lights on dimly, blinkers did not work, or the radio)The guy who was selling it did not want to put any money in to it so he left it as is. He said it needed an alternator, so I figured I would get it home and check it out for grounding, etc, before I got one. The battery terminals were corroded pretty bad so I cleaned them up. I took the from the negative lead of the battery that was loose. I cleaned it up, tighten it and put the battery back on and everything then worked great to my suprise. I was hoping it was a bad/loose ground and I got lucky. Check your negative terminal under the battery, maybe that may be your problem too.
