Power Module


The [1][2]power module houses the circuits needed to power the ignition coil and fuel injector, and energizes the automatic shutdown (ASD) relay which activates the fuel pump, ignition coil and power module itself. The module also receives a signal from the distributor and relays this signal to the logic module. If no distributor signal is received, the ASD relay is not activated and power is shut off from the fuel pump and ignition coil. A voltage converter in the power module reduces battery voltage to a regulated 8 volt output which powers the distributor as well as the module.
