Diesel, Single Generator

WARNING: This page is about a different car, the 2009 Ford RV Cutaway, 2009 Ford Econoline, 2009 Ford E450 Super Duty, and 2009 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.

The diesel single generator system consists of the generator mounted on the top right of the engine. A 110-amp generator with a 2.79:1 pulley ratio is standard. An extra heavy-duty option is available which includes a 140-amp generator with a 2.79:1 pulley ratio. The 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 engineering number and the parts catalog.

In the diesel single generator system, with the key in the ON position, voltage is supplied through the charging system warning indicator (in the Instrument Cluster (IC)) 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.
