I have a 94 k2500 6.5 diesel with a electrical issue. I have 14 volts at both batteries and at alternator but as soon as I turn something on, volt gauge in dash drops to 12 volts. Verified 12 volts at cigarette plug. If I go back out to engine, voltage is close to 14 volts at batt/alt. What would cause losing 2 volts from engine bay to interior?? Thanks
