The EL Falcon (1996–1998) represents the final evolution of Ford Australia’s “classic era” Falcon before the heavy electronic shift of the AU. Mechanically familiar, electrically straightforward, and refreshingly easy to diagnose, the EL’s electrical system is often regarded by enthusiasts as one of the most reliable and serviceable setups ever fitted to a Falcon.
System Overview
The EL Falcon uses a 12-volt negative earth electrical system built almost entirely around conventional wiring and discrete components. Electronic control is present, but limited almost exclusively to engine management.
Key components include:
- Conventional alternator with internal voltage regulator
- Maintenance-free lead-acid battery
- EEC-V engine management system (PCM)
- Traditional fuse and relay architecture
- Mechanical throttle linkage (cable-operated)
- Minimal body control integration
- Basic instrument cluster with analogue emphasis
Unlike later BA/FG systems, there is no multiplexed body network and no CAN-bus architecture. Each system largely operates independently, which makes both diagnosis and modification far more approachable.
Alternator and Charging System
The EL Falcon uses a conventional internally regulated alternator that operates independently of any advanced PCM control logic.
Typical specifications:
- Output range: ~85–100A depending on engine variant
- Internal voltage regulation
- Belt-driven mechanical design
- Fixed charging curve with minimal electronic adjustment
Common part numbers:
- Ford OEM EL alternator assemblies (I6 4.0L variants)
- Bosch replacement alternators (widely used aftermarket option)
- Denso remanufactured units
Known issues:
- Voltage regulator failure leading to overcharging or undercharging
- Bearing wear due to age and heat cycles
- Diode pack faults causing battery drain when parked
- Reduced output at idle under heavy accessory load
Despite their simplicity, EL alternators are generally robust and predictable in failure behaviour.
Battery System
The EL Falcon uses a standard maintenance-free lead-acid battery as factory specification.
Typical specifications:
- 12V maintenance-free lead-acid battery
- Moderate cold-cranking capability
- Designed for standard electrical loads of the era
Common part numbers:
- Ford OEM EL battery group sizes (commonly NS70 or equivalent depending on variant)
- Century MF lead-acid batteries
- Exide maintenance-free replacements
- Bosch S3/S4 equivalents
Known issues:
- Sulphation from short-trip driving
- Reduced performance with aged alternators
- Cold-weather cranking weakness when aged
- Voltage drop affecting ignition and fuel delivery consistency
Battery health is critical, but the system is forgiving compared to later electronic-heavy Falcons.
Wiring and Engine Management
The EL Falcon’s electrical system is anchored by Ford’s EEC-V engine management system, which controls fuel delivery, ignition timing, and emissions systems.
Key components include:
- EEC-V PCM (Powertrain Control Module)
- Basic ABS module (where fitted)
- Transmission control (in some variants, integrated logic)
- Analogue-style instrument cluster with limited digital integration
- Traditional relay and fuse distribution
Unlike later Falcons, there is no BCM managing body-wide electrical functions. Most systems are directly wired and independently controlled.
Benefits:
- Extremely straightforward diagnostics
- High tolerance for electrical faults
- Minimal dependency on module communication
- Easy modification and repair
Limitations:
- Less refinement in accessory behaviour
- More wiring complexity than earlier EB/ED models
- Limited integration between systems
- No advanced diagnostic feedback compared to later platforms
Lighting and Accessories
The EL retains a largely conventional approach to lighting and accessory systems.
Features include:
- Manual headlight operation
- Electric windows and mirrors (depending on trim)
- Central locking systems (vacuum and electric variants depending on configuration)
- Interior lighting circuits with simple delay functions
Common issues:
- Headlight switch wear and heat damage
- Window regulator failure (mechanical and electrical wear)
- Earth point corrosion causing flickering or intermittent faults
- Relay fatigue in headlight and accessory circuits
Because systems are simple, faults are typically easy to isolate and repair.
Infotainment and Interior Electronics
Infotainment in the EL Falcon is minimal by modern standards but consistent with its era.
Features include:
- AM/FM radio head units
- Single or multi-disc CD players (higher trims)
- Optional premium audio systems
- Basic dash integration without digital display dependency
Known issues:
- Head unit capacitor failure or display dimming
- Speaker deterioration over time
- Wiring fatigue in door loom connections
- Limited aftermarket integration without adapters or fascia kits
This simplicity is one reason EL Falcons remain popular for straightforward audio upgrades.
Electrical Weak Points
Even though the EL is widely regarded as reliable, age has revealed a few consistent weak points.
1. Alternator Wear
Regulator and bearing failure are the most common issues.
2. Earth Points
Corrosion leads to intermittent electrical faults and poor starting behaviour.
3. Wiring Harness Ageing
Door looms and engine bay wiring insulation can become brittle.
4. Switchgear Degradation
Headlight and window switches are common wear items.
Upgrade Potential
The EL Falcon is one of the most modification-friendly Falcons electrically due to its simplicity.
Common upgrades include:
- High-output alternators for audio systems
- AGM battery conversions for improved stability
- Upgraded grounding kits
- Modern double-DIN head unit conversions
- LED lighting upgrades (with relay considerations where needed)
It’s simple, predictable, and highly serviceable. Where newer Falcons rely on communication networks and control modules, the EL relies on wiring, relays, and mechanical logic.
