Test DSAM

1. Trace red power source lead from DSAM to harness connection. Separate connector and connect red lead of a

DC voltmeter to harness terminal. Trace ground lead (green) from SAM to grounding screw. Connect black

voltmeter lead to eyelet terminal of ground lead or ground screw/bolt. Check voltage with key switch in both

START and RUN positions. A minimum of 7.25 volts must be present.

a. If correct voltage is not measured, connect black voltmeter lead directly to negative (-) post of battery and test

voltage again in both key positions. If correct voltage is now indicated, check ground circuit connections. If

Incorrect voltage is measured. Voltage Connect black voltmeter lead directly

to negative (-) post of battery and test

voltage again in both key positions.

If correct voltage is still not indicated,

check harness connector terminal for

a good connection and crimp to lead.

Then trace power source circuit back

through harness, key switch, etc.,

looking for any poor connections, or

faulty circuits.

following, or use TT-5152 provided with tester. If DSAM tests bad, replace it.

3. Reattach DSAM leads, verifying a snug fi t at ignition module terminals. If any connections do not feel snug,

disconnect lead, lightly pinch female terminal with a pliers, and recheck fi t.

4. Seal base of ignition module connections with GE/Novaguard G661 or Fel-Pro Lubri-Sel dielectric compound.

Beads should overlap between two connections to form a solid bridge of compound. Do not put any compound

inside connectors.

5. Test for spark to be sure system is working, before you reinstall blower housing. If there is still a spark problem on

one side, replace that ignition module and recheck spark.
