Electrical System and Components
a. If correct voltage is not measured, connect
black voltmeter lead directly to the negative
(-) post of the battery and test voltage again
in both key positions. If correct voltage is
now indicated, check the ground circuit
connections. If the ground screw/bolt or any
other fasteners in the ground circuit are black
(oxide-coated), replace them with zinc plated
(silver colored) fasteners.
b. If correct voltage is still not indicated, check
the harness connector terminal for a good
connection and crimp to the lead. Then trace
the power source circuit back through the
harness, key switch, etc., looking for any poor
connections, or faulty circuits.
2. Disconnect all of the SAM leads, isolating it from
the engine. Test the SAM according to style with
tester 25 761 21-S (tests ASAM style modules
only), or tester 25 761 40-S (tests both ASAM and
DSAM style modules). Use the test instructions
following, or those provided with the tester. If the
SAM tests bad, replace it.
3. Reattach the SAM leads, verifying a snug fit at the
ignition module terminals. If any connections do
not feel snug, disconnect the lead, lightly pinch the
female terminal with a pliers, and recheck the fit.
4. Seal the base of the ignition module connections
with GE/Novaguard G661 (see Section 2) or
Fel-Pro Lubri-Sel dielectric compound. The beads
should overlap between the two connections
to
form a solid bridge of compound. Do not put any
compound inside the connectors.
The 24 584 15-S ignition modules have a
separator/barrier between the terminals. On
these modules, seal the base of the terminal
if any portion of it is exposed, but it is not
necessary to have overlapping beads of
sealant between the connections.
5. Test for spark (Test 2) to be sure the system is
working, before you reinstall the blower housing.
If there is still a spark problem on one side, replace
that ignition module and recheck spark.
To Test – Using 25 761 21-S Tester
ASAM (only) Test Procedure
NOTE: The SAM must be at room temperature when
tested. Disconnect all of the SAM leads,
isolating it from the main wiring harness and
the ignition module(s). Testing may be
performed with the module mounted or
loose. The figures show the part removed
from the engine for clarity.
Figure 8-10.
1. Connect the tester to the SAM as follows:
Attach:
A. The yellow tester lead to the long yellow module lead.
B. The brown tester lead to the long brown module lead.
C. The red tester lead to the red module lead.
D. The green tester lead to the green module lead.
Caution: Do not allow the alligator clip leads to touch
each other.
