METHOD OF MEASUREMENT
Using an Approved Diagnostic System
1. Swit ch off all elect rical loads and ensure t hat t he i gni ti on is off.
2. Connect the current probe t o t he approved di agnos ti c s yst em.
3. Calibrate t he probe.
4. Ins t al l a clamp around the bat tery lead/junct ion box l ead.
5. Go t o t he Quies cent Current Tes t ing s ect ion.
