Electrical 2-3Section 2: ElectricalCharging MarginsGenerator output varies with engine speed and ambient temperature as it is illustrated in theGenerator Output Section. The worst case for police vehicles is when the vehicle is idling for longperiods of time on a very hot day. Lower engine speeds while idling, coupled with high underhoodtemperatures that may approach 93°C (200°F), combine to minimize power output from thegenerator. At the same time, electrical demand on the vehicle is often at its highest because theair conditioner loads are added to the usual electrical loads experienced in emergency situations.Vehicle Component Electrical LoadsVehicle component electrical loads are shown in the table below. Not all features are powered allthe time, so actual vehicle loads on the power supply system will vary.2007 Police Interceptor Modifier Guide, 2006
