Hello,
Which way do you test for parasitic draw, ammeter between the negative cable and battery terminal or positive cable and terminal?
I always thought it was on the + side, as all current must originate there, but I figure that based upon resistances, dissipation as heat, etc., not all has to return to the negative.
Yet Ive heard elsewhere to do it on the negative side.
Does it matter? Is one way better than the other?
