if you keep expierenceing voltage drop while the car is running. chances are that you have a short somewhere in the main power system. check all your connections to the engine, the starter etc. also have your battery checked, if your battery has gone bad, this too could be a problem. if the new alternator doesnt fix it, i sugest you do a full electrical diagnostic. check all of your connections vs. positive and ground. check all the fuses and relays in the fuse pannels.
