Hi if you think the light fault is a low Battery voltage then take a voltage reading one or two every day so you can compair fault and low voltage readings .

You want a Battery voltage of 12.5 volts good

12.00 to 11.75 and gremlims will creap in 11.7 or ther abouts on load when trying to start and if will fail to .

Have you considered fitting a Battery monitor then you can check battery voltage when you in the house if you can see your vehicle on the drive just google battery monitor.

Note AGM chargers required for agm battery as a standard lead acid charger wont work voltage to low needs 14.8 volts volts to charge agm batterys

Please read the whole thread, it has been fault found and pinouts traced, it was water/washer fluid egress into the internal fuse box
