Having problem with alternator (or something else I believe) and keeping the volts up. I have changed the alternator to a new 108 amp and a 120 amp and still cant keep it up at 14.

Actually, cant get it up to 12 now, after I have swapped them out. Engine will crank and run with no problem, just when I am at a stop light/sign or using accessories the amp meter just drops and the car will stall when I release the brake or if I am waiting long.

Any help?

Get the alternator load tested with a VAT machine and double check all wiring conections at the alternator.
