I used Google to translate this questions, correct me if I'm wrong

''hi, i am from indonesia contry. I have a problem with charging on mercy e250. in the vehicle only 12.6 volts is idle + ac load. but if the main light is turned on it will be 13.7 volts''


I have never heard of a problem where turning on the main light can provide 13.7 volts.. is it the other way around?


Anyway, there is obviously a problem with the circuit connection of your battery and lights. I would suggest, checking the Voltage with the car turned off and the main lights turned on to see what happens. Let me know once you test this
