What should the battery voltage be in a Honda Odyssey?
Battery voltage should be around 12.6v. When the alternator is charging it should be 13.5-14.5v. I’ve seen the intermittent battery light when high loads are placed on the alternator like both AC units, radio, etc. Then when loads are reduced the battery light goes out. Checking the voltage with the battery light on is the key here.
How does the ECM work on a Honda Odyssey?
If everything was in spec, the voltage regulator removed the ground by providing positive source voltage on the L circuit. However, on late model vehicles, the ECM sends source voltage to the L circuit. If a problem occurs, the voltage regulator will pull the voltage on the L circuit to ground.
What kind of seats does the Odyssey have?
The Odyssey offers premium features throughout the cabin, like the available Magic Slide® 2nd-row seats and hands-free access power tailgate, to help you load up the family and all your gear with ease. Elite shown with Gray Leather. Magic Slide® 2nd-row seats standard on EX and above.
What can I do with my Honda Odyssey?
You can also use buttons on the wheel to switch between Honda’s system and Apple CarPlay or Android Auto, or even change the audio from whatever is playing on the radio to whatever your passengers are watching / listening to on the back TV screen.
What causes an alternator to go over base voltage?
If you are getting more than 2 volts above base voltage, most likely your alternator is over-charging the battery or the battery is faulty. Other potential problems are a faulty voltage regulator or a problem in the charging system wiring.
How to know if your alternator is working properly?
1 Check the drive belt or serpentine belt. Look for signs of wear or damage like cuts, shiny spots or missing chunks under the belt. 2 Also, check the belt tensioner for proper operation and damage. It should rotate freely. 3 Make sure the alternator is properly mounted. 4 Check the alternator for noises. …
What happens when the diodes in an alternator go bad?
Alternators use diodes to rectify alternating current produced by the alternator into direct current. When one or more diodes go bad, the alternator can cause all kinds of problems. AC voltage leak can cause your lights to dim and drain power from your battery, for example.

Why does the battery light come on when the alternator is on?
If the battery light is on when the voltage is above 13v then something is still wrong with the alternator as the switch for the light is in the alternator. I had this with a Denso alternator on a 2006 Ody. Installed new alternator and it worked great except after about 20 seconds the battery light came on even though charging voltage was 14.5v.

Why does my Honda Odyssey have a red battery light?
2011 Odyssey LX, about 110k miles, no problems at all until the red battery light (that is supposed to indicate a problem with charging) has been coming on intermittently starting a week or so ago, along with the CHANGE bATT message.
