I'm assuming this alternator has an internal regulator, but it's not listed on oreilly as having one.

It looks the same as this one that is listed as having an internal regulator. I had a new dead battery, and I just used the LMC plug to bypass the external regulator. Hoping to check the basics before looking for loose ground wires and drains. Battery died in about two days.
