i remember reading a post around here mentioning DIYing the big-3 would benefit ppl who are running high output alternators rather than those with the low amp alts such as myself (70amp). i believe its true as the factory wiring thats used with the alternator to battery would be large enough to support whatever the alt could handle. by adding additional large wires, it would only give 2 uncessary paths of current. if this is wrong, please correct me.
to my question: i have an 70 amp factory alt in my car still and would like to know if i will notice dramatic improvements by DIYing the big-3?
