IntroductionBackgroundThisisasupplementtothedocumenttitled“MGTCElectricalCircuits”,coveringjustthe1949MGTCEXUmodel.TheTCwasupgraded,electronicallytocomplywithvariouscountry(mostlytheUnitedStates)lawsandregulationsregardingautomobiles.Amongthesewereelectricalturnsignals,sealedheadlights,andlicenseplateilluminationlights.Foreaseofuse,I’veincludedallthecircuitsoftheEXUinthisdocumenteveniftheyareidenticaltothenon-EXUmodel.CircuitsthatAretheSame
! ChargingandAuxiliaryPower! Ignition! IgnitionWarningLight! PetrolPump! ScreenwiperMotor
CircuitsthatNeworRevised
! Headlights! SideandTailLights! Horn! Dash/PanelLightsandClock! PetrolWarningLight! MapLights! DirectionalIndicatorLightsandStopLights
CircuitsthatHaveBeenEliminated
! FogLamp! StopLights(NowintegratedinwiththeDirectionalIndicators)! InspectionSockets
Again,Idonotprofesstobeanyformofexpertonelectronics.AlltheinformationIampresentinghereisextractedfromnumerous.Shouldyoufindanerror,pleaseletmeknowatTCStormer@comcast.netandIwillupdatethedocument.
