ENGINE ELECTRICALIgnition System TestingIgnition system components can be individually tested by measuring their internal resistance and insulation toground. These checks must be done with a digital volt/ohm meter. Compare the readings obtained to the valueslisted on the chart. Actual values may vary up to ± 10% between like components. Any readings outside the spanshould be considered questionable.NOTE: The stator coils can be checked without removing them from the <strong>engine</strong>. Simply disconnect the connectorplug in the stator-to-COI wire and check the resistance values between the wire colors listed below. Consult thestator schematics shown on the next pages.* Indicates a system that incorporates a white COI-to-stator ground wire. These systems will indicate continuitybetween the exciter/pulser wires and ground.EXCITER COILPULSER COILCheck Wires Value Check WiresIValueSINGLE CYLINDER MODELS BrownlWhite 123 Ohms Not Applicable19<strong>85</strong>-Current Star/Star LTto Black/RedStar Lite.TWIN CYLINDER MODELS BrownlWhite 164 Ohms Not ApplicableAll EC34-2PM (Pulseless)to Black/RedAll EC4O-PUSOPL thru 1989 BrownlWhite 164 Ohms BrownlWhite 14S0hmsAll EC44-2PM.to White to Black/RedIAll EC40PUSOPL 1990 to currentBrownlWhite 164 Ohms Not ApplicableEC4SPL (Pulseless)to Black/RedAll ECSOPM 1990 to currentAll EC44-3PM (Pulseless)/All ECSOPM thru 1989 BrownlWhite 164 Ohms BrownlWhite T 17 Ohmsto Whiteto Black/Red* Indicates a system that incorporates a white COI-to-stator ground wire.
