I have a 2001 5.3 Vortec out of a Tahoe in my 49. With my Walbro inline fuel pump running, electric fan, and the AC on my gauge drops just below 13 volts. Without the AC on it charges at 14 volts. Am I ok or should I be thinking about a high output Altenator? I have a new battery and don't want to drain it down.
