Test Timing Advance (DSAI and DSAM only)

1. Make a line near edge of fl ywheel screen with a marking pen, chalk, or narrow tape.

2. Connect an automotive timing light to cylinder that had good spark.

3. Run engine at idle and use timing light beam to locate line on screen. Draw a line on blower housing next to line

on screen. Accelerate to full throttle and watch for movement of line on screen relative to line on blower housing.

If both cylinders had good spark, repeat test on other cylinder.

Condition Possible Cause Conclusion

1. Remove blower housing from engine. Inspect wiring for any damage, cuts, bad crimps, loose terminals, or broken

wires. Check that connections are oriented properly on terminals of modules.

2. Disconnect leads from ignition module(s) and clean all of terminals (male and female) with aerosol electrical

contact cleaner to remove any old dielectric compound, dark residue, dirt, or contamination. Disconnect spark

plug leads from spark plugs.

3. Using a multi-meter, check that a proper ground is established between ground (black) lead of DSAI module

(closest to spark plug lead) and a known good ground location on engine.

4. Turn key switch to ON position and check for 12 volts at center/power (red) lead terminal of DSAI module. Use

same ground location for multi-meter as in checking for timing advance.
