So my first issue with the Regal (LS swapped). Car hasnt really held a charge since coming home. It would sit between 7-10 days between starts. So figured it was due to it sitting. But now that I'm out driving it more, it doesnt hold a charge. Pretty much have to jump it or keep battery charger on it if it sits overnight. Battery is brand new and had it tested at 2 different Oreilys yesterday and both said its perfectly fine. 28 mile drive to suspension shop, sat inside overnight and they had to jump it the following day, same thing when I brought it home. Now what I'm leaning towards and not sure how to tell if thats the issue. Original alternator was a 4 pin, I purchased a 250 amp high output alternator for my subs/amp. That alternator is a 2 pin, but wired up using a 1 wire pin, see link. Prior to the swap and having the original alternator, I never had this issue and thats why I'm leaning towards alternator plug. Thoughts and how would I could I test if the 1 wire pin is the issue? Also using below on positive of battery
