I have a '70 Coronet with a 440 and am getting ready to tackle the wiring system. I want to use a higher amp alternator since I will be using electric fuel pump, fans, ac, etc. It looks like I am pretty much starting the entire electrical system from scratch. (looks like a couple or more fires in the past 39 years). I have a trunk mounted battery and want to install a shutoff switch of course. Every alternator I find that has the amperage requirements is a one wire and/or costs 350 bucks. Anybody have any suggestions or guidance so I don't waste a bunch of money and time? Thanks for your help.
