Ifthekillswitchisintherunpositionandthemotorcycle
doesnotcrankatall,thenextthingtocheckisthefuse.The
fuseisaccessibleunderneaththeleftbodypanel.
Ifthefuseisopen(blown),youwillneedtoreplaceit,but
beforeyoudo,you
shouldfindthereasonthefusebleworit
islikelyyouwilljustblowthefuseagainwhenyoureplace
it.Ourmostfrequentlyencounteredreasonforablown
fuseisthewireclusterbehindtheheadlight.Sometimes
theconnectorbootsslideawayfromtheconnectorand
permita
shorttoground(it’sthefirstplaceI’dlook).Ifthat
isnottheproblem,examineallofthemotorcycle’swiring
anduseamultimetertoidentifyanyshortstoground.
Ifthefuseisintactandthemotorcycledoesnotcrank,next
checkthebattery .Pleaseseeourbatterymaintenance

tutorialforthis.
Ifthebatteryoutputisappropriateandtheconnectionsare
ingoodshape,checkthestarterrelay.Useamultimeterto
confirmvoltageisreachingtherelayandtherelaycloses
whenthestarterbuttonispressed.Ifthestarterrelaydoes
notreceivevoltagewhenthe
starterbuttonispressed,the
problemisinthecircuitfromthestarterbutton.Usea
multimetertoisolatethefaultandcorrectanyanomalies.If
thestarterrelayreceiveselectricalenergybutitdoesnot
closethecircuittothestarter,checkthestarterrelay
connections.Iftheyareintact
andfreeofcorrosion,replace
thestarterrelay.Pleasecallusat9094450900ifyouneeda
