Description
DESCRIPTION
Figure 1 INTEGRATED POWER MODULE
The Integrated Power Module (IPM) is a combination of the Power Distribution Center (PDC) and the Front Control Module (FCM). The IPM is located
in the engine compartment, next to the battery.(Figure 1). The PDC mates directly with the FCM to form the IPM. The PDC is a printed circuit board
based module that contains fuses and relays, while the FCM contains the electronics controlling the IPM and other functions. This IPM connects directly
to the battery positive through a four pin connector. The ground connection is through two other connectors. The IPM provides the primary means of
voltage distribution and protection for the entire vehicle.
Operation
OPERATION
All of the current from the battery and the generator output enters the Integrated Power Module (IPM) through a four- pin connector on the bottom of the
module. Internal connections of all of the power distribution center circuits is accomplished by a combination of bus bars and a printed circuit board.
