Get the charge rate measured straight out of the regulator, (still plugged in) I bet you will have voltage drop issues. Get a proper auto electrician to sus it if out of your depth.
You can do voltage drop tests from the negative and positive feeds out of the regulator to where the drop is if so. My mates was losing about a volt across the light relay.
