Ranger 2WD V6-245 4.0L VIN X SFI (1997)
Fusible Link: Description and Operation
The fuse link is a short length of insulated wire integral with the engine compartment wiring harness. It is several wire gauges smaller than the circuit that
it protects. The fuse link for the Generator (GEN) is a 12-gauge gray wire.
There is a fuse link in the generator output circuit and a fuse in the voltage regulator A circuit.
The fuse link is designed to burn out, thus protecting the wiring when heavy reverse current flows, such as when a booster battery is connected
incorrectly, or a short to ground occurs in the wiring harness.
A burned-out link may have bare wire ends protruding from the insulation, or bubbled insulation with illegible identification. If it is hard to determine if
the link is burned out, perform a continuity test.
Service fuse links are brown, green or black depending on usage. All fuse links have a flag moulded on the wire or on the terminal insulator. Color
identification of the flag or connector is gray 12-gauge wire. The illustration shows a typical fuse link installation.
