I'm new here and would like to say hello, I have a 1998 jaguar xj8, I owned it since 2002 so I no my car, but here is something I can't shake the BATTERY NOT CHARGING LIGHT here is what I did to cover most areas, I bought a new battery, new wires for battery, new Bosch alternator, new multi-plug for alternator, and cleaned all the grounds I could find on the car, all the fuses are good, Please tell me what is left to do after all this, any help is fine, THANK YOU SO MUCH...
