Question type: General

1 Answer


The ELD (electric load detector) is part of the fuse box. You can't replace it without replacing the whole box. ---- The ELD is essentially a current transformer that monitors the amount of current draw the car is pulling from the battery. This amount varies from time to time depending on what you have turned on (various electrical devices). The ELD will output .1 - 4.8 volts to the ECU. This reference voltage is what tells the ECU to increase or decrease the field strength in the alternator, which in turn bumps up the output of the alternator.
