Thanks very much for your thorough explanation...it's much clearer.

So, if I've not had any problems starting my motor with a 12v, and my only concern is getting enough current to my electrical devices while the motor is running, i.e. MSD box, fans,fuel pumps, etc., then I should be okay to run a 12v battery but with an alternator that puts out enough amps, i.e. 95 or so?
