coool!! Bob's the man!

 

As promised I made these measurements a week ago but didn't have time to post them till now.

Here's what I did - I disconnected the battery ground wire and inserted a 1-foot piece of 10-gauge wire as a shunt resistor. 10-gauge is about .001 ohms per foot, so it will cause a 1 millivolt drop for each amp, which I measured with a digital voltmeter.

I then disconnected the alternator output so all the current being used would have to come out of the battery. To calibrate my shunt I measured the actual current drain of the parking lights, then measured the shunt voltage and compared the two. The readings below are corrected by that calibration factor.

Thanks for taking the time to measure all that Modifry!
It must have taken a lot of time and patience.
I really appreciate all your help on this matter.

Do you think we should ask to have this added to the Audio FAQ?

 

Wow....great info....this should put a dent in the "ricer" arguements on the BMW boards about the 6000watt systems. Great job!

 

sweet... Thanks Bob...
