[QUOTE="Chops , post: 642145, member: 59693"] A quick test: A car battery is comprised of 6 cells at 2.1v each, hence 12.6v for a charged battery. A battery won't charge unless the charging voltage > than batt voltage, most charging systems are regulated at 13.8v. With lights on at idle, you should have ~13.8v at the battery, If not, your alt. is defective. [/QUOTE]
