Section 61 (Charging System - Generators & Regulators - Dual Generators): Description

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2003 Ford RV Cutaway, 2003 Ford Econoline, 2003 Ford E550 Super Duty, 2003 Ford E450 Super Duty, and 2003 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: References to Econoline include Cutaway and RV Cutaway.

System consists of a pair of 110-amp generators with internal voltage regulators, 2 batteries, Powertrain Control Module (PCM), warning indicator and wiring. Generators operate independently through internal voltage regulation. PCM monitors both generators, and is able to set diagnostic trouble codes and control charge warning indicator operation. PCM generator control is limited to disabling lower generator during glow plug operation to avoid over-voltage damage to glow plug circuit. Generators have different size pulleys, and are not interchangeable.

Charge warning indicator should illuminate with ignition on, engine off. Charge warning indicator should not illuminate with ignition off, or with engine running. Generator and regulator cannot be serviced separately, and must be replaced as an assembly.
