So lately I've replaced my alternator voltage regulator. Battery seems to drop really low after 3-4 days. Replaced the battery with Bosch S5 74Ah 700cca.
While driving, the car is showing above 14V. So I assume charging is OK.
I've gotten around to measuring the current drawn and I need some guidance.
This is the way i've connected it;
red (10A on the meter) towards negative on chassis
COM to battery negative
After I lock the car, it's displaying 30-ish for a minute, then drops to 11.5-12 (I'm assuming miliamps - i'm using the meter in 200mA mode):
After additional 10 minutes, it drops to 3.3-3.7:
Even 3 hours later, seems to be the same:
So..what is killing the battery???
