With Multimeter Test Procedure

NOTE: Use an in-line ammeter between the battery positive or negative post and its respective cable.
1. Insert the test leads in the input terminals shown.
2. Turn switch to mA/A dc.
3. Disconnect battery terminal and touch probes as shown.
4. Isolate circuit causing current drain by pulling out one fuse after another while reading the display.
5. Current reading will drop when the fuse on the bad circuit is pulled.
6. Reinstall fuse and test components (including connectors) of that circuit to find damaged component(s).

NOTE: Do not start vehicle with clip on cable. The current reading (current drain) should be less than 0.05 amp. If it exceeds 0.05 amp, it indicates a constant current drain which could cause a discharged battery. Possible sources of current drain are vehicle lamps (engine compartment, glove compartment, luggage compartment, etc.) that do not shut off properly.
