being rather involved in projects at home pro tem , I rarely get out in the car so it sits in the garage
recently had a thought for seeing what happens to the battery as it drains
took a cigarette lighter adaptor from my box of bits , piece of twin wire to a double connector block , popped it on the dash with my digital meter
now if my theory is correct if you open a door the only thing that is activated is a couple of interior lights so I sit in , shut the door , plug in my device and measure the voltage [ on a D2 the front cigarette lighter socket seems to be constant live ]
after a minute or so the lights go out and the the voltage starts to rise , arriving at a steady state after a couple of minutes ..as one would expect
in my case the voltage is decreasing by a steady .02 volts/day
has anyone else checked this voltage drop ? is it what one would expect from a system that has no faults ? the bigger drain that I have previously suffered seems to have disappeared
