A similar ground-side test on a mower with a slow-
cranking starter motor can be conducted between the
engine block and the negative battery post.
See Figure 7.62.
1. With the starter engaged, this machine exhibited a
voltage drop reading of 0.312 volts, indicating a
poor ground connection.
2. Individually, these readings should lead a technician
to inspect the connection between the solenoid and
the ground path on the first mower (e.g. mounting
hardware, green wire with eyelet beneath head of
solenoid mounting bolt), or the engine and the
frame on the second mower (e.g. loose or rusty
engine mounting bolts).
3. If both of these readings were found on the same
mower, a common point in the system would be the
primary suspect (e.g. poor connection between neg-
ative battery cable and frame).
Applying this principle to the positive side of the sys-
tem:
IMPORTANT: Ultimately, all positive current will
find its way from the positive post of
the battery to the negative post.
1. To check hot-side voltage drop: set the DMM to
measure 12V DC. See Figure 7.63.
2. Make a good electrical connection between the red
(+) probe and the positive post on the battery.
3. Make a good electrical connection between the
black (-) probe and the suspect point of the circuit.
4. Power-up the circuit in question.
5. The voltage indicated on the meter is the power that
is not following the intended path back to the nega-
tive battery post.
