I am getting a ”Charging System Fault” warning with no symptoms at all: no charging or starting issues. It will randomly illuminate and then after awhile resolve and goes out - at night, in the daytime, with everything on or off, rain or shine. I have a new battery (it was time anyway) and the system was reset to accept the new battery. Battery is up to specs and the alternator is putting out on specs. Had it to the shop twice where it of course behaved!!! I am suspecting the battery sensor cable (Two light gauge wires in a little sheath and to connector ends - $90 bucks!
