I'm replacing my stock 70amp alternator with a 200 amp one. What do I need to do to the stock electrical system for everything to run smoothly?
The alternator came with a external voltage adjustable regulator. Do I need anything else?
Also, the regulator is adjustable from 12-14 volts. Should it be set at 14volts?

you need not do anything, just make sure to replace/upgrade your wire from the alternator to your battery(ies) you should also set the voltage regulator to read no higher than 14.4 volts at about 3000 rpm, do not set it at idle otherwise when you rev the motor you could send 16 volts through your electrical system causing some damage
