Hello all, I purchased the boat last November. (1997 Regal Commadore 292, twin 5.7). The port engine is not charging 11.67v. The alternator has been tested, the batteries are brand new, I cleaned and lubed with dielectric grease all connections I could find. I swapped coils and alternator, no change. Oddly enough, the orange wire at both alternators are disconnected with black tape covering the connection. I don't know why. Would this stop the port engine from charging? If so, why would the starboard engine be charging at 13+ volts?
