Yamaha XS360 400 force the plug in if it is too tight as this may crack the cover INSPECTION Connect a fully charged 12 volt battery 1 Take out the two screws and remove across the solenoid low tension leads and check for continuity across the high tension the starter side cover 2 Check electrical continuity between terminals with an ohmmeter or self con STARTING SYSTEM the commutator and armature core using a tained test light If there is no continuity multitester or test light and battery If conti replace or repair the solenoid The starting system consists of the starter nuity exists the armature coil is grounded 4 Check for continuity across the low ten motor and clutch the solenoid and the and the complete starter motor unit must be sion terminals with an ohmmeter or selfhandlebar mounted starter switch When the replaced powered test light Resistance should be 3 5 button is pressed the electrical circuit to the 3 Check for continuity between all of ohms If there is no continuity the primary solenoid is closed and the solenoid is acti the commutator segments Continuity must winding of the solenoid is broken and the vated sending the battery current directly to exist in each case unit must be replaced the starter motor The starting system is 5 If starter trouble began just after the 4 Check continuity between the brush quite reliable and it is unlikely that any major that is wired to the stator coil and the starter starter button housing was disassembled or problems will arise motor cable Lack of continuity indicates an moved for any reason check the connections open circuit in the stator coil and the starter at the switch as they may have come adrift motor unit should be replaced Resistance Testing should not exceed 0 05 ohms ELECTRICAL COMPONENTS If the starter will not operate switch on the 5 Examine the carbon brushes for damheadlight and observe its intensity If it is Horn dim when the starter is not being operated check the battery connections and recharge 1 If the horn fails to sound check that the battery If the headlight doesn t light there is 12 v on the brown horn lead If there check the fuse the battery connections the isn t check for a broken wire ignition switch and its connections and 2 If the brown lead checks out check that check the continuity of the wire between the the pink wire is grounded when the horn ignition switch and the battery button is pressed If it isn t check the horn button If the headlight is normally bright press the starter button and observe any changes 3 If the wiring is satisfactory replace the horn If the headlight dims when the button is pushed it indicates that the starter motor is Checking for continuity between commutator drawing current If it does not dim i e noth segments Brake Light ing happens the starter motor is probably not getting any current In this case suspect age to the contact surfaces and measure their 1 If only one of the two brakes fails to ac the starter solenoid length Replace the brushes as a set if either tivate the brake light the problem is proba To check the solenoid and starter button one measures less than 6 mm 0 24 in or if bly confined to that switch the easiest test is to bypass the unit com they are damaged in any way 2 If neither switch will activate the brake pletely by disconnecting the battery lead 6 Brush spring tension should be mea light first check the brake light bulb If it is from the solenoid and connecting it directly sured with a small pull scale Replace the in workable condition check that there is 12 with the aid of a high tension jumper cable springs if they have weakened to less than v on the yellow brake light lead to the starter motor terminal If the starter 550 g tension 3 If there is voltage on the yellow lead 7 The mica undercut of the commutator check for voltage on each brown lead at the motor works the solenoid or starter button is should be maintained at 0 7 mm 0 027 in brake light switches defective and must be replaced If the motor still fails to work the motor it Any carbon deposits should be cleaned out of the commutator grooves and a piece of hack self may be the cause of the trouble Taillight Starter motor faults are rare but several saw blade or the like used to increase the un dercut depth if necessary 1 If the taillight will not work check the things can go wrong 8 Polish the commutator with fine bulb first If the starter spins freely but the engine 2 If it is satisfactory check for voltage on doesn t turn over suspect the starter motor emery cloth and then clean it thoroughly before installing the blue lead If there is voltage on this wire clutch 9 Measure the diameter of the commu check for a good ground black wire If the engine will tum over only very slowly and without a great degree of predict tator The armature should be replaced if the ability some possible causes include a low measurement is less than 27 mm 1 06 in Turn Signals 10 Check the condition of the armature or almost dead battery oil which is too thick 1 If only one side fails to work check for weather conditions extreme cold or bad bearings and replace them as a set if any both bulbs on that side first bearings in the motor itself Wom bearings damage is noted 2 If the bulbs are operable check for 11 Check the condition of the oil seal and could cause the armature to contact the field voltage on the green right or brown left coils which will effectively short out the replace it if the seal lips are cracked or wom 12 Unsealed bearings should be lubri leads If there is voltage here check the starter Usually repeated attempts at start ing will result in the starter motor getting cated with 20W or 30W motor oil before as grounds black leads 3 If neither side will work check for volt very hot Other possible causes of starter sembly Coat the lips of the oil seal with age on the brown white lead at the handlebar motor trouble include wom brushes a wom white grease
