Non-charging help 89 Dakota

I too have a Shelby Dakota #660. My computer took a dump but I was able to clone it to get the truck working again. So the 1989 computer has two boards in it. The top board with the small connector is the board that controls the alternator. The second board withthe large connector is the engine management. It is possible the Alt board is bad. The capacitors are like likely bad just due to there age.
