Charging system light is on. I've replaced the battery and alternator which took care of the problem for a day but now It's dimly lit. I'm looking for an electrical diagram to trace what could be causing this issue.

Hello,

It does sound like it could be a wiring issue.

Have you tested the alternator to see what the output to the battery is?
It is possible to have a fault with the warning light itself.

I have attached the wiring schematics for the charging system for your vehicle.

Please let me know if you have any questions.
Thank you.
