How does the Honda Charger Charger system work?
Honda Dual Mode Charging systems Starting with many 2008 Honda and Acura vehicles use a dual-mode charging system. The system consists of an Electric Load Detector (ELD) to determine vehicle electrical load, an alternator with an internal voltage regulator, and communication with the ECM.
What to do if your Honda Accord battery won’t charge?
Use a voltmeter to check the battery’s output. If the reading shows 14.5 volts or less when the car is running, it should be changed. Figure 1. An overused battery. If the battery is worn out, first have it replaced with a new one. This will pinpoint other mechanical problems because those depend on a battery that is in good condition.
How many wires are involved in a Honda Charger?
The fourth is the charging rate input to the ECM (the blue or yellow wire).The fifth is an output from the ECM (white with a yellow stripe).This is the control circuit that turns the alternator on through the voltage regulator. There are a total of three wires to the computer that are involved in the charging system.
How does the Honda alternator charge the battery?
During startup and periods of low electrical loads or after the battery has been recharged after startup, the ECM will set the charging voltage at a lower 12.4-12.9 volts. Honda maintains voltage at this low rate once the battery is fully charged in order to maintain battery charge.

When did Honda start their car charging system?
From approximately 1988, the vehicle ‘s computer plays an important role in the charging system, and we must take its actions into account when diagnosing a charging system problem. For this particular tech tip, we will be using a 1989 CRX with a 1.6l engine as an example.
