Error code on Federal '88 300E

Today my Check Engine light came on twice. When I got home this afternoon, I turned on the ignition without the engine running and read 30% at pin 3. After starting the engine it gave a nice 49%.

A year or two ago MBDoc was kind enough to send me a sheet of paper with the trouble codes. I can't find that sheet of paper anywhere now. It seems like I remember that 30% meant that all was well.

If 30% is a trouble code and someone has the information to tell me what it indicates I would appreciate the help.

Thanks in advance,
