12-1 CHARGING SYSTEM 1995 BRONCO For diagnostic information, refer to section 1400 of the Service Manual. With voltage applied, regulator is activated, allowing current to flow from sense A circuit ' ' to alternator field coil. Generator generates v an AC outputwhich is converted to a DC out- V put byarectifierassem blyinternalto genera- tor, and issuppliedtovehiclethroughtheB+ terminal. S (stator) circuit is used to feed back avoltage signal from generatorto regu- lator, this voltage(typically half battery volt- age), is used by regulatorto turn offindicator.
