leads and put the meter in the circuit and read off the current drain (if
you have the car door open then imobilise the interior light in some way.
The drain should be no more than about .006 amps (this is usually enough to
run the clock and the back up memory for the radio).

If it is higher than this then remove each fuse in turn to see if you can
locate the circuit with the drain.
