I did some more diagnosis today and I'm sure its the alternator -- When the engine is cold, the alternator will put out 13.9v and 13.4-13.7v with ALL accessories on. As soon as it heats up and I've driven for 15mins, it plumets to as low as 12.3v averaging around 12.6-12.8v.

To keep things simplistic, can I simply run one additional 4ga wire directly from the alternator to the battery and leave the stock wiring alone with the 143a alternator? (or will I need to change the stock wiring anyway due to the alternator using different connectors?)

I have so many other projects going on right now that I don't have to time to DIY my own cables etc. Looking to buy some premade cables that I can just hook up and be done with it.
