The AU Falcon fuse box contains multiple circuit protection devices. This guide identifies fuses and procedures for replacement.
The 1999 Ford AU Falcon fuse box is located under the dash on the driver's side, providing central protection for electrical circuits. The box contains multiple fuses rated for different amperage capacities, each protecting specific vehicle systems. Fuse selection ensures appropriate overcurrent protection without nuisance blowing during normal operation. Oversized fuses allow excessive current, risking fire and damage. Undersized fuses cause frequent nuisance blowing, preventing normal circuit function. Fuse cartridges have color coding corresponding to amperage ratings. Brown indicates 7.5A, red indicates 10A, yellow indicates 15A, blue indicates 20A, and other colors represent different ratings. The AU Falcon electrical system operates at 12-14.5 volts DC with alternator charging during engine operation. Battery voltage provides power for starting and accessories during engine shutdown. Multiple relays in the fuse box distribute power to major loads like cooling fans and fuel pumps. Starter circuits bypass the main fuse box, using battery cables with separate fusible links. Ground connections throughout the vehicle provide return paths for current. Proper fuse selection prevents electrical fires and component damage. Diagnostic procedures identify problem circuits when components malfunction. Additional fuses protect aftermarket accessories installed by owners. Weatherproofing the fuse box prevents corrosion and electrical faults.

Frequently asked questions
Which fuse protects the headlights in AU Falcon?
Headlights typically use 15A fuse in the main fuse box. Locate the fuse diagram label inside the fuse box cover.
Why does my fuse keep blowing when I replace it?
A short circuit or overload exists downstream. Do not use a larger fuse. Identify and repair the underlying fault.
Can I use a higher amperage fuse than recommended?
Never. Oversized fuses prevent protection of wiring and components, causing fire hazard.
What should I do if I cannot locate a specific fuse?
Check the fuse box cover diagram showing all circuits. Online forums provide detailed AU Falcon specific documentation.
Are there multiple fuse boxes on the AU Falcon?
Yes, the main box under the dash and possibly an engine bay distribution box. Consult the owner's manual for all locations.
