What fuse link protects the 1996 charging system output circuit?

Fuse Link J, a 12 gauge gray fusible link, is in the circuit between the battery/starting system feed and wire 38 BK/O going to the generator B+ terminal.

What wire colors are used in the charge indicator circuit?

Wire 16 R/LG runs from the ignition switch (through connector C269 and splice S206) to the instrument cluster, and wire 904 LG/R runs from the cluster through connectors C202F/C202M and C133F/C133M to the voltage regulator. The generator output is wire 38 BK/O.

What resistor is in parallel with the charge indicator lamp?

A 510-ohm resistor is shown inside the instrument cluster in parallel with the charge indicator bulb, at connector C250.

How does the voltage regulator turn off the charge indicator lamp?

Per the diagram's note, the S (stator) circuit feeds a voltage signal (typically half battery voltage) from the generator back to the regulator, which the regulator uses to turn off the indicator.

Where are the charging system grounds located?

The battery negative is grounded via BK wires to G101 (body) and G103 (engine).

This is page 12-1, "Charging System," a 1996 ("96") Ford wiring diagram scanned from a factory-style electrical manual and uploaded to a 1996 Ford Bronco gallery. The diagram shows the complete charging circuit: the battery (grounded via BK wires to G101 body ground and G103 engine ground), Fuse Link J (12 gauge, gray) feeding circuit 38 BK/O to the B+ terminal of the internal-regulator generator/voltage regulator assembly, and the R circuit branching to the starting system (page 20-2). The generator internals are drawn, including the rectifier, regulator with sensing and switching circuits, and the F screw and A screw terminals, with connectors C153 and C154. The indicator circuit runs from the ignition switch (hot in START or RUN, switch testing on page 149-2) through connector C269, wire 16 R/LG, splice S206, into the instrument cluster (page 60-4) charge indicator lamp with a parallel 510-ohm resistor at connector C250, then out on wire 904 LG/R through connectors C202F/C202M and C133F/C133M to the regulator's I terminal. A callout explains regulator operation: AC output rectified to DC at B+, with the S (stator) circuit feeding back roughly half battery voltage to turn off the indicator. Circuit 36 Y/W is also shown.
