TEST PROCEDURE
1. Test each battery of a series pair, then proceed to batteries of next series pair.
2. To find series pair of batteries, find pairs for which the negative terminal of one battery is connected
by a cable to the positive terminal of another battery. This makes the two batteries a series pair. For
example, in figure below, batteries A and B are a series pair , and batteries C and D are also a
series pair.
3. To test battery A or B, clamp current probe around cable connecting battery A and battery B. Point
arrow on current probe in direction of negative post connected to the cable.
4. The test probe cable W2 is first connected to battery A for testing battery A.
5. The test probe cable W2 is then connected to battery B for testing battery B. (Current probe in same
place as for testing battery A).
6. To test battery C or D, clamp current probe around cable connecting battery C and battery D. Point
arrow on current probe in direction of negative post connected to cable.
7. Connect test probe cable W2 to battery C to test battery C.
