To test DSAM using spark advance module (SAM)
tester:
NOTE: DSAM must be at room temperature when
tested. Disconnect all of DSAM leads, isolating it
from main wiring harness and ignition module(s).
Testing may be performed with module mounted
or loose.
NOTE: Do not allow alligator clip leads to touch each
other.
1. Connect tester to DSAM as follows:
Attach:
● Yellow tester lead to long yellow module lead.
● Brown tester lead to long brown module lead.
● Red tester lead to red module lead.
● Black tester lead to green or black module ground
lead with eyelet terminal.
● Pink tester lead to short yellow or pink module
lead.
● Brown tester lead with black band or terminal to
short brown module lead.
2. Check DSAM part number, stamped on end of tester
housing, noting last two digits. Using those numbers,
refer to table below or tester faceplate to determine
test number to be used.

3. Depress tester button repeatedly until correct test
number appears on display. After a few seconds,
test number will flash three times and 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 condition of part.
4. If you get a negative (-) sign instead of numerical
sequence, and/or an F at end of test cycle, recheck
all connections, check condition of tester battery and
repeat test. If you get negative (-) or F sign again in
retest replace DSAM.
Allow 15-20 seconds for tester to clear and reset itself
between tests or if test is interrupted before completion
of test cycle. Otherwise, a false reading may be
displayed in form of a (-) or a faint (8).
Tester is powered by a 9-volt battery. Most SAM’s are
designed to operate down to a minimum of 7.25 volts.
If tester battery drops below that level, incorrect test
readings will result. Tester battery should be checked
periodically by connecting a DC voltmeter between red
and green lead wires, with tester connected to a DSAM.
Start appropriate test sequence. While test is running
monitor voltage reading on voltmeter. If voltage drops
below 7.5 at any time during cycle, 9-volt tester battery
must be replaced. Use an extended life (alkaline) battery.
To replace battery, remove outer set of screws on
faceplate and carefully lift panel from body. Unplug
connector and pull battery (with mounting tape) off back
of tester. Attach connector to new battery and mount
battery to case with double-backed tape. Reinstall
faceplate and secure with four screws.
