During this study break, I finally got time to dig deeper into my overcharging issue. After alot of testing, I narrowed the issue down to the alternators sense wire. It had significant voltage drop, forcing my voltage regulator to over compensate on charge.
The harness which housed the wire seemed to have rubbed on the sump. It was very hard to see, but after cutting back the harness I found the sense wire had a small green dot on it. Cutting back the insulation exposed about 5mm worth of completely corroded wire. (Unsure how to attach photos sorry)
After replacing this wire, all the issues were sorted. No more overcharging and no dash battery light. Thanks to everyone who previously commented suggestions!
