So many ways of saying it and of course someone has to be wrong.

I am sorry for being wrong if that makes you feel better and keeps the thread going Cheesy

Mr. Logic divided his ohms by the volts, rather than vice versa.

amp clamp reading drift


Sorry for a noob question, but what's this? This is the first time i've heard of this.

Logic, did you ever solve this? The info you gave is just a small piece of the picture.

Did you ever load test the battery?
How many amps was the parasitic drain?
Did you check the voltage drop across the fuses to locate the source of the drain?
There are charts online that help give you a rough estimate of how much current is passing through the fuse without having to disturb the circuit.

Going through tech school to earn my ASEs and learn the basics; please excuse my noobish questions.

Drift.

The Amp clamp and not just the one used here are prone to drifting above the zero line.

We always zero the clamp near to the circuit as possible, also snap the jaws open closed a couple of times to get ride of any magnetic build up in the jaws this is known as Degaussing.

After a period of time the zero will rise so the amp clamp will need to be removed from the circuit and the above procedures redone.

Hope this helped Wink
