Verify and mark which flywheel timing line corresponds with the listed ignition timing from the chart at thebeginning of this unit. Refer to the method of using a dial indicator for verifying timing marks described onpage 4.12.13. Connect an accurate tach and a good quality timing light to the engine.cBlower HousingStationaryLinesNOTE: Acceptable varianceis usually one line on eitherside of the dial indicatedblower housing stationaryline.o14. With the engine running at 3000 RPM, point the timing light at the blower housing stationary lines. If theflywheel mark aligns with the correct stationary line or anywhere in the acceptable +/- variance, the timing iscorrect. If the timing is not correct, follow steps 4 through 7, re-checking the timing after each step.15. Disconnect the ignition kill cirQuit by disconnecting the black wire at the COl module.16. Check the exciter coil resistance and replace if necessary.17. Replace the COl module.18. Replace the flywheel.4.15 8/94
