Unplug dc power connection then remove right side panel check for loose connections on on alternator, check distance of speed sensor to speed sensor disc you should no more than 3 credit card distance between them. Next remove the black wire from the B+ terminal on the alternator, then remove the brown wire from the field terminal on the alternator.Place a short wire with alligator clips between B+ and field terminals start stepping for about 10 to 15 second you should full resistance in that case its the upper console that if not replace alternator
