What wire color and gauge is the charging circuit from fuse link J to the generator B+ on a 1995 Bronco?

Circuit 38, black with orange stripe (BK/O), fed through fuse link J which is a 12-gauge gray fusible link.

What circuit runs from the charge indicator to the voltage regulator?

Circuit 904, light green with red stripe (LG/R), passing through connectors C202F/C202M and C139F/C139M.

How does the charge indicator turn off according to this diagram?

The stator (S) circuit feeds a voltage signal back from the generator to the regulator — typically half battery voltage — and the regulator uses this voltage to turn off the indicator. A 500-ohm resistor is shown in parallel with the indicator.

Where do I find diagnostic and related information for this charging system?

Diagnostics are in section 14-00 of the Service Manual; power distribution and ignition switch are on page 13-3 (switch testing page 149-2), the instrument cluster on page 60-4, and the starting system on page 20-1.

What grounds are used in the 1995 Bronco charging system?

G101 (body ground) and G103 (engine ground), both connected with black (BK) wires from the battery negative side.

This is page 12-1, "Charging System," from the 1995 Ford Bronco electrical/vacuum troubleshooting manual (EVTM). It presents the complete charging system wiring diagram, showing the battery, generator/voltage regulator (with internal rectifier, regulator, and sensing/switching circuits, plus F screw and A screw terminals), fuse link J (12-gauge, gray), the ignition switch (hot at all times, with START/RUN/OFF/ACC/LOCK positions), and the charge indicator in the instrument cluster with a 500-ohm parallel resistor. Wire circuits are labeled with circuit numbers and colors: circuit 38 BK/O from fuse link J to the generator B+, circuit 16 R/LG from the ignition switch through splice S206, circuit 904 LG/R to the regulator I terminal via connectors C202F/C202M and C139F/C139M, circuit 36 Y/W, and circuit 4 W/BK on the stator feedback. Connectors shown include C269, C250, C153, C154, C202, and C139; grounds are G101 (body) and G103 (engine). An explanatory note describes regulator operation: voltage on the sense A circuit energizes the field coil, AC output is rectified to DC at B+, and the stator (S) circuit feeds back roughly half battery voltage to turn off the charge indicator. Cross-references point to section 14-00 for diagnostics, page 13-3 for power distribution and ignition switch, page 60-4 for the instrument cluster, and page 20-1 for the starting system.
