I'm trying to troubleshoot a battery drain issue with my 55, You leave the car a couple weeks with the battery plugged in the battery will drain, sometimes just one week will drain it, and according to the GEN light slowly getting brighter and brighter while driving at night the generator evidently isn't charging enough to keep up with the headlights I guess.


Anyway I'm trying to get a base reading with my multimeter and I looked on youtube to find out how to take the readings. My initial readings with the car running was at about 6.10v with the motor idling, and then when I turned the headlights and heater fan on it'd go down to 5.79v. I went for a drive and came back and the reading was about the same but here's the thing, I went to start it a few minutes later in my driveway and the battery is dead. Question is, if the battery is dead why is it still reading 6.7 volts on the meter? OR am I just completely misusing the meter?
