3. Depress the tester button repeatedly until the
correct test number appears on the display. After
a few seconds, the test number will flash three
times and the test will begin. A reverse numerical
sequence will be displayed, starting with a 6 and
progressing down to 1, followed by a "P" (pass)
or "F" (fail), indicating the condition of the part.
See Figures 7-14 and 7-15.
4. If you get a "-" sign instead of the numerical
sequence, and/or an "F" at the end of the test
cycle, recheck all of the connections, check the
condition of the tester battery* and repeat the test.
If you get the "-"or "F" sign again in the retest
replace the DSAM.
Allow 15-20 seconds for the tester to clear and reset
itself between tests or if the test is interrupted before
completion of the test cycle. Otherwise, a false reading
may be displayed in the form of a "-" or a faint "8".

** The tester is powered by a 9-volt battery.
Most SAM's are designed to operate down to
a minimum of 7.25 volts. If the tester battery
drops below that level, incorrect test readings
will result. The tester battery should be checked
periodically by connecting a DC voltmeter
between the red and green lead wires, with the
tester connected to a DSAM. Start the appropriate
test sequence. While the test is running monitor
the voltage reading on the voltmeter. If the
voltage drops below 7.5 at any time during the
cycle, the 9-volt tester battery must be replaced.
Use an extended life (alkaline) battery.
To replace the battery, remove the outer set of screws
on the faceplate and carefully lift the panel from the
body. Unplug the connector and pull battery (with
mounting tape) off the back of the tester. Attach the
connector to the new battery and mount the battery
to the case with double-backed tape. Reinstall the
faceplate and secure with the four screws.
Most engines are equipped with a 15 amp regulated
charging system. Some have a 25 amp regulated
charging system. See Figure 7-16, 7-17, and 7-18 for
the wiring/charging system diagrams of ignition
systems.
NOTE: Observe the following guidelines to
avoid damage to the electrical system and
components:
• Make sure the battery polarity is correct. A
negative (-) ground system is used.
• Disconnect the rectifier-regulator plug and/
or the wiring harness plug before doing any
electric welding on the equipment powered by
the engine. Also, disconnect all other electrical
accessories in common ground with the engine.
• Prevent the stator (AC) leads from touching or
shorting while the engine is running. This could
damage the stator.
