Need help with alternator
I have a 72 k20 and I need to upgrade my alternator so I can run dual electric fans. The current alternator has 1 wire which from what I read means its internally regulated. I also have on the front of my truck on the core support an external voltage regulator. When I first got my truck I had problems with dead batteries and once I replaced the external voltage regulator I havent had a problem since. So it makes me think its hooked up? The single wire from the alternator runs to the fire wall into a plastic harness I assume it goes to the relay inside the cab? Im confused on what alternator I need to purchase. Do I just get a single wire one and use a thicker wire and run it from the alternator to the relay? Do I need to remove the external regulator or by pass it as Ive seen in a few forums
