How does an ELD work in an alternator?
This unit reads the amperage load directly from the battery and in-turn sends a varied voltage signal to the PCM which regulates the field signal to the alternator. The ELD is a three wire unit mounted in the fusebox with a primary voltage lead, a primary ground, and a load output lead which is used by the PCM.
Where is the ELD unit on a Honda?
They know when you need that extra help and when it’s not needed. Honda’s answer to this is the ELD (Electrical Load Detector). Since the early ’90s, Honda vehicles have used an electrical load detector (ELD) unit in the under-hood fuse/relay box.
What to do if Honda alternator is not working?
The first step for many of us when a car is brought in with a charging problem is to charge and test the battery. On Hondas with a fully charged battery, you won’t see any alternator output unless you introduce a load by turning on the headlamps, blower motor and rear defrost.
How much does it cost to replace Eld on Honda Element?
After searching through threads to get the Part Number and TSB for the replacement of the ELD to fix the Dimming Headlight problem I decided to put a post together that has it all in one place (Sticky???). Ok now for my $.02. The fuse box is kind of a pain to remove.

Why is my Eld not working on my Honda Accord?
According to Honda for the Accords, they are issusing statements that it’s a normal part of the Honda’s running in that the ELD has a slight delay from when it detects additional load and when it is making the switch to higher output from the alternator. I was surprised to see a “fix” listed here in the E forum.
What’s the reference voltage for Honda Eld Gonzo?
The ELD will vary the output between .1 to 4.8 volts to the ECU. This reference voltage is what tells the ECU to increase or decrease the field strength in the alternator. Even though the voltage level is still very important in today’s cars, the amperage draw throughout the different systems is monitored to a greater degree than in years past.
