3 Ignition System Blck Sttor Models Red Sttor Models Adpter Module Description The ignition system is lterntor-driven with distriutor-less cpcitor dischrge. Mjor components of the ignition system re the flywheel, sttor ssemly, trigger ssemly, switch ox, ignition coils nd sprk plugs. The sttor ssemly is mounted elow the flywheel nd hs 2 coils. The flywheel is fitted with permnent mgnets inside the outer rim. As the flywheel rottes, the permnent mgnets pss the sttionry sttor ignition coils. This cuses the ignition coils to produce AC voltge. The AC voltge then is conducted to the switch oxes where it is rectified nd stored in cpcitor. The trigger ssemly (lso mounted under the flywheel) hs 2 coils. The flywheel likewise hs second set of mgnets (locted round the hu). As the flywheel rottes, the second set of permnent mgnets psses the trigger coils. This cuses the trigger coils, in turn, to produce n AC voltge tht is conducted to n electronic switch (SCR) in the switch ox. The switch dischrges the cpcitor voltge into the ignition coil t the correct time nd in firing order sequence. Cpcitor voltge is conducted to the ignition coil primry. The ignition coil multiplies this voltge to vlue high enough to jump the gp t the sprk plug. The preceding sequence occurs once-per-enginerevolution for ech cylinder. Sprk timing is chnged (dvnced/retrded) y rotting the trigger coil position in reltion to the permnent mgnets on the flywheel hu. Red Sttor Models Red sttors require n dpter module tht gets connected etween the sttor nd switch ox. Without the dpter module, the voltge supplied y the sttor would exceed the voltge cpility of the switch ox R1 DECEMBER 1996 ELECTRICAL AND IGNITION - 2A-1

4 Ignition Trouleshooting WARNING DANGER - HIGH VOLTAGE/SHOCK HAZARD! Do not touch ignition components nd/or metl test proes while engine is running nd/or eing crnked. STAY CLEAR OF SPARK PLUG LEADS. To ssure personl sfety, ech individul sprk plug led should e grounded to engine. Before trouleshooting the ignition system, check the following:. Mke sure tht electricl hrness, lnyrd switch, ignition switch, nd mercury switch re not the source of the prolem.. Check tht plug-in connectors re fully engged nd terminls re free of corrosion. c. Mke sure tht wire connections re tight nd free of corrosion. d. Check ll electricl components, tht re grounded directly to engine, nd ll ground wires to see tht they re grounded to engine. e. Check for disconnected wires nd short nd open circuits. Trouleshooting Test Equipment Multimeter / Tester Sprk Tester Checking for Loss of Sprk The use of n inductive timing light while crnking or running the engine will show whether there is sprk present or not. The timing light will not show the strength of the sprk. Incorrect sprk strength my not llow the sprk plug to fire under compression The use of sprk gp or sprk gp ord will give visul indiction of the strength of the sprk. Norml ignition sprk is BLUE in color. A YELLOW or RED sprk indictes wek ignition. 2A-2 - ELECTRICAL AND IGNITION R1 DECEMBER 1996
