Battery Test Probes
To connect test probes to the battery pole:
1.
Use the inner tip of the test probe to touch the target surface.
2. Push the test lead to set-back the inner tip, until both the inner tip and the outer tip
are fully connected to the target surface. This will ensure a proper 4-wire
connection to the battery terminal.
Note
Stable and correct readings are shown only when both the inner tip
and the outer tip of the test probe are fully connected to the battery
posts. To get more accurate battery internal resistance reading, do
not connect the test probes to screws. See Figure 3-2.
Examine for open fuse before m Ω measurement by connecting the
outer tips of both probes. If the m Ω reading changes from OL to
dashes and then backs to OL, the fuse is good. If m Ω reading
remains as OL, the fuse is open and needs a replacement.
In this function, the voltage between the positive and negative poles
of a battery must be < 60 V. A voltage >60 V causes the fuse to
open.
