If you get an inductive amp meter, be sure it measures DC as the lower end ones only measure AC. Extech and Tenma made decent general use test equipment.
Be sure to get one with small tongs as industrial level meters are too big for most automotive use.

$ 50 for a lower end but still useful DC clamp ( on sale from $ 100 )

When using a general use amp clamp, the last few miliamps can be difficult to chase due to the meter floating around.
