Default '94 SSE Parasitic Short

I checked current between negative battery terminal and cable. I get any where from .78 to 4.5 amp draw. I get .78 if I immediately unscrew negative terminal and check, but I get a 4.5 amp draw if I leave it disconnected for 5-10 minutes and then go back and recheck.

I check all the fuses and and I have only two that are drawing any current. One draws .15 another draws .01, all the rest draw 0. I can't see how a .15 or a .01 draw would cause a .78 to 4.5 draw on the battery. I think one fuse was for the radio and instrument cluster and I forget what the .01 fuse was. I wrote them down but it is in the car. I unpluged both fuses, and I still get a .78 to 4.5 amp draw on the battery so these can be eliminated.

Ok, let'* see how smart all you are.

What troubleshooting should I do next?

sounds like a sticky relay...try unplugging relays one at a time.
