The charging voltage of a Honda alternator can vary depending on the specific model and year of the vehicle. However, it is generally expected to be between 13.9 and 14.8 volts, with 14.2 volts being considered optimum. It’s important to note that the charging voltage can be affected by various factors, such as the state of the battery and the electrical load on the vehicle . If you are experiencing issues with the charging system, it is recommended to have it checked by a qualified mechanic to diagnose and address any potential problems.

What is a bad alternator voltage reading?
If the alternator is working well, the multimeter reads somewhere around 13-14V. If the noted value is excessively high (greater than 15V), it may indicate that the alternator’s voltage regulator has gone bad.
Is 12.3 V too low?
For a 12v lithium battery: It is important to monitor the voltage while charging devices and ensure that it does not drop below 10Volts. Otherwise, there’s a potential problem. For the typical old-school lead acid battery, you should be seeing at least 12.3V.
What should my alternator voltage be when charging?
The standard alternator designed for road vehicles has a voltage regulator mounted to the back of the alternator and set to a single charge voltage of 14 or 28 volt. This is sufficient for a car battery, which is rarely (if ever) discharged.
Is 12.3 volts fully charged?
12.5 volts – Your battery is at a healthy state of charge, but we’d recommend re-checking it within a few days to ensure the voltage hasn’t dropped any further. 12.1 – 12.4 volts – Your battery is partially discharged and should be recharged as soon as possible, using a suitable battery charger.
Is 14.8 volts too high for alternator?
What voltage is too high for an alternator? For standard passenger vehicle 12v systems, anything avove 14.8v is worrisome. Anything below 13.6v will not adequately charge the battery.
Is 15.2 volts too high for alternator?
If the voltmeter reads between 14-15 volts then the battery is normal. But if the battery reads over 15 volts or less than 13 volts, then there might be a problem with the alternator. The alternator is over charging the battery or not giving enough charge to the battery.
Is an alternator charging at 15 volts bad?
If the alternator is working well, your multi-meter should read somewhere in the vicinity of 14 volts (typically 13.8-14.2). If it is reading excessively higher than 14 volts (greater than 15 volts) it is possible that the voltage regulator on your alternator is faulty or going bad.
Is 14.7 volts too high for alternator?
Voltage shouldn’t be exceeding 14.7 – normally when all things are working properly you’ll be in the 13.9-14.4 range (this is on a car without MSA – MSA cars will behave slightly differently).
Is 12 volts bad for an alternator?
Alternator should raise system voltage above 13 volts. If it doesn’t (or does at very high RPM) then alternator is defective. A properly operating alternator has an output of 13.4 volts up to 14.2 volts without any load, so I would suggest to replace the alternator.
What should a Honda alternator charge at?
During heavy electrical or mechanical loads (i.e., if the AC clutch is engaged), the ECM will set the charging voltage to 14.4-14.9V (high output mode); during startup and light electrical load conditions, the ECM will set the charging voltage to 12.4-12.9V (low output mode).
