FACILITATE EIS.  THE STARTER AND BATTERY ARE NOT ONLY LARGER, BUT MORE
ROBUST AS WELL.  THE ALTERNATOR IS MORE POWERFUL, AND SO IS THE
SOPHISTICATION OF THE ELECTRICAL DEVICES SUPPORTING THEM.  ONE OF THE MOST
IMPORTANT SUPPORT DEVICES IS THE ELD ELECTRONIC LOAD DETECTOR.  ELDS HAVE
BEEN IN USE FOR MANY YEARS TO MEASURE THE CURRENT DRAWN BY THE ACCESSORIES
AIR CONDITIONING, LIGHTS, ETC.  THE ELD ALLOWS THE ENGINE CPU KNOWN BY A
VARIETY OF NAMES TO ACCURATELY ADJUST THE AIR/FUEL MIXTURE, THUS INCREASING
FUEL ECONOMY.  THE ELD IS OFTEN INCORPORATED INTO THE MAIN DISTRIBUTION
FUSE PANEL.  HOWEVER, ON VEHICLES EQUIPPED WITH EIS, THE ELD IS LOCATED IN
THE NEGATIVE LEAD OF THE BATTERY FIGURE 1, OR AT THE BATTERY CONNECTOR
FIGURE 2.  THIS PLACEMENT FACILITATES COULOMB COUNTING, WHICH IS AN
ESTIMATED MEASUREMENT OF THE BATTERY STATE OF CHARGE SOC.  MEASURING
CURRENT DURING STARTING PROVIDES AN ESTIMATE OF THE BATTERY RESERVE
