Before using an ohmmeter on a component/circuit dways disconnect the battery. Although a 12 voh test lamp may be used for fault finding, never use a test lamp on circuits that contain electronic components. s i n k damage 10 these components may result.

Familiarize yourself with the operation of the circuit to be tested. Also the lapout of the components in that circuit Make reference to rhe appropriate section within this Chapter. 3. Always consider the symptoms and then decide on the most advantageous and convenient poim a which to commence your investigation. The unnecessary remwal of items of trim is costly and damage could result Fitting electrical accsssorks When fming electrical accessories it is recommended.: that they are wired from the fuseboard and that the fuse is of the correct size and rating. Atso, it is essential that the correct size of cable is used. Spare fuse positions are available on the fuseboard. They are designed to take fuses of either 10 amperes (small size fuse) or 20 amperes rating. Do not under any cirurrnstances rsplaca an existing fuse with one of a Jargar size or higher rating. If the accessory incorporates an in-line fuse it is essential that the in-line fuse is of a lower rating than that on the fuseboard.

Fining relays eliminmes the need for heavy duty type switches and enables light duty types of switches te be used. An example of hew B circuit containing a relay operates is shown in figure M2-1.When the comaerr of the switch (irem 1) ate made the control circuh of the relay (indicated by the amwed lines) provides a 12 voh positive feed to the relay coil (item 2) *us energizing the coil. Energizing the coil causes the normally open wntaca marked 30 and 87 to close. f his then allows a 12 vott positive feed from the supply circun fuse (item 3) to be fed through the comscts to supply the component (item 4). Retays are also used to provide changeover f u n n ~ o n si.e. 10change from one circuit to another. An example of how the changeover function is accomplished.is shown in figures M2.2, M2-3, and M2-4. Wih bmh switches (A and B) in the open position (seefig. M2-2)bulbs 1 and 2 are extinguished. By closing the conram of switch B (seefig. M2-3) s 12 vok positive feed is supplied from the supply fuse (hem 3) through the nomally closed relay contacts 30 and 87a to illuminate bulb 2. Operation of switch A (seefig M2-4) energizes the relay coil. This transfers the feed from relay contacts 30 and 87a to contaas 30 and 87. this causes bulb 2 to be extinguished and bub 7 to illuminate. Locstion With two exceptions relays are interchangeable. The stop tamp failure relay is of a different type and cannot physically be interchanged with other relays on rhe ear. The staner relay on cars fined with a blue Lucas {round bodied] type relay must not be interchanged with other relays on ?he car. figure M2-5 shows the position of the relays fitted to early Silver Spirit, Silver Spur. and Mulsanne ,-a Fig. M2-1 Switching relay - energized --i- Fig. M P - 2 Changeover relmy - isolated r [excluding Turbo) cars. Figures M2-6 ta M2-9 inclusive are applicable to Silver Spirit Silver Spur. Comiche. Bentlty Eight. Mulsanne {including f U*) a d Comimnral cars prior to 1985 model year cars. The fining of relays is dependent upon individual car specification. For example on cars conforming fo a North American specification which prohibits the fining of rear fog lamps. the appropriate relay will be omitted. The relays ere positioned in groups. Access to ?he relay group on the driveis side of the car (interior nrlrys) requires tht removal of the knee roll trim. Two relays are mounted on each from seat mechanism, access is gained by removing the apvropriafe seat cushion Removal of the lvggage companrnent right-hand mm carpet will g k access to all the relays in the luggage compartment Fig. M2-3 Changcr-overrelay - unenergized Fig. M2-4 C h a n p w e r rely - ansgbsd Sunion M2 WORKSHOP MAMUAL M2-5 A Relays Silver Spirit.
