This guide is a fairly simple one on updating the old alternator. Originally I tried to get a bigger alternator for the car but was given a maximum sized one of 55 Amps as “that is the only one that will fit the car”. BS I thought but took it anyway. Long story short, with the amount of electronics I am now running I wanted a larger alternator, I decided to go for any early commodore alternator as long as it was larger and found this “reconditioned” 70 Amp alternator on eBay from a VK commodore, when I got it though it was an 85 Amp alternator, all the better.
