Single Generator

WARNING: This page is about a different car, the 2008 Ford RV Cutaway, 2008 Ford Econoline, 2008 Ford E450 Super Duty, and 2008 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.

The single generator system consists of the generator mounted on the top right of the engine (diesel) or top center of the engine (gas).

The gas engines use a 115-amp generator with a 2.52:1 pulley ratio. An extra heavy-duty option is available for both the 5.4L and the 6.8L engines. It includes a 135-amp generator with a 2.52:1 pulley ratio.

The diesel engine uses a 110-amp generator with a 2.79:1 pulley ratio.

An extra heavy-duty option is available that includes a 140-amp generator with a 2.52:1 pulley ratio. The standard and extra heavy-duty generators are similar in appearance and use the same connectors, making them interchangeable. Identification between the different generators can be carried out by referring to the generator part number and the master parts catalog.

In the single generator system, with the key in the ON position, voltage is supplied through the charging system warning indicator (in the instrument cluster) through the I circuit to the voltage regulator. The regulator grounds this circuit and the charging system warning indicator is illuminated. When the engine is started, the regulator removes the ground on this circuit and the charging system warning indicator turns off.
