Any one have any ideas on how the 78 MGB charging system works. I have replaced both the battery and altenator in my sons 78. I am only getting 12 volts across the altenator, I am under the impression I should be getting 13.5. My 74 gets 13.5 Does the 78 have a different system, The car was wired by the previous owner. Old wires and new wires are still in the car>could he have missed something???Next stop is the shop unless anyone has any ideas on what I have missed. By the way should the 78 not have an earth ground? I cann't find it on this car. /ubbthreads/images/graemlins/cowboy.gif
