I have a 1955 Chevy with a 700r4 trans. and 350 motor. I put on a single wire alt. Now I noticed that I'm pulling 14.4 volts upon exceleration. Is this to much? I also noticed that at night my rear running lights go out and brake lights go out. I'm wondering if my light switch is acting like a voltage req. and when the voltage gets to high it opens the circuit. 55 chevy light switches have that protection in it.
