2003 Silverado has a draw that is .75 amps to the alternator from the battery when everything is turned off. If I unplug the alternator from the harness the draw stops and it drops to zero. I also have a battery indicated on the cluster that stays on, as well as the PRNDL. Not sure if they are related but both still happen when the other is unplugged. What will cause this and should my next step be sending the cluster in for repair? Also I have already reflowed the solder on the cluster resisters.
