00042
1. Verify all battery cable connections are clean and tight.
2. Turn battery disconnect switch to the ON position (TM 5-3805-293-10).
3. Using a digital multimeter, measure voltage between positive post (Figure 1, Item 3), and negative (Figure 1,
Item 1) post of the machine batteries. Monitor and record voltage.
4. Using a digital multimeter, measure voltage between positive post (Figure 1, Item 3) of machine battery and
machine ground (Figure 1, Item 2). Voltage should not be less than 1 volt of value recorded in step 3.
a. If voltage is equal to value recorded in step 3, proceed to step 5.
b. If voltage is less than 1 volt of value recorded in step 3, machine negative battery cables OK, proceed to
Test 2.
