just checked the battery and alternator with the engine off and I'm getting 11.93 to the battery and 11.94 to the alternator. The alternator is an OEM part and I have an external voltage regulator. No electrical work done on the vehicle recently...just clutch replacement. Could it be the voltage regulator?

I took the battery to AutoZone and they did a full charge and said nothing was wrong with the battery however its draining. The car was running and after letting it sit for an hour it's dead again. Could it be something other than the battery/alternator?

Hi All, I'm new to this forumn. I have a 1980 280zx that is losing power between the alternator and the battery. The alternator measures 14.8 volts (car on), at the battery it measures 13.5, battery measures 11.5 (car off). When starting it's a slow start but once it fires up it runs without cutting off. I unhooked the battery and the car stays on so I think the alternator is good. Could this be a voltage regulator problem or something else? Any help would be appreciated. On another note does anyone know what motor swaps are good for this car? TonyT
