Type 404 Cars

Description

The 12 volt electrical system IS a single wit,,, type c it'cuit having the positive (+) pole of the battery earthing to rh" engine and car. Cllrrcot is sllppliedby a two brush dynamo in conjunction with a voltage regulator and 00

~utornatic c ur out. Two 35 amp fuse s an: fined in the acccssoric" circuit.

Wiring Diagram karly type can;). Fig.187. Wi"ing Diagram (later type cars). Fig.18B.

Dynamo

The dynamo is belt driven and is mounted in 11 swivcl~ ling cradle on the left hand side of the engine and cooled by a fan at the rcar of the driving plllley.

Starter Motor

T he starter mOtor !located on the right hand side of the engine) is of nOl'mal design with a Bcndix typ" inertia pinion on the worm s haft to engage the nywhcel tecth . The di rection of rotation is COUnter clockwi "c wh en viewed from the front of the car. Control of the starter motor is via the "emote solenoid switch mounted on the right side of the bulkhead.

Voltage Regulator and Fuse Box

Early type cars.

T he voltage regulator and CUt Out are housed on a com mon base (covered by a single moulded cover) mounted on the control panel in the banery bay. Sec Fig.ISO. Below the COVer is the m ain terminal junction block. Two fuses (indi cated by the markings 'lIux' and' AUI( Ign') on the regulator unit cOver protec t certain of the accessories .

Fig. 189. Vultage regu lator anti Cut oUl (early can!)

Later type cars.

The voltage regulator and Cut out are housed on a COmmon base !covered by a single moulded cover) mounted On the electrical control panel in the battery bay, see Fig.190. The main electrical terminal connections are mounted on the base adjacent to the cover. A block mounted be low comains the two fuses.

The voltage regulator controls the output of the dynamo according tothe load on the battery and its state of charge. When the b~tlery is in a low state, the dynamo output is high. No adjustment to the regulator or C Ut out is normally ,·equired. Should however any adjustme nt become necessary it should be e ntrusted to a recognised Lucas agent.

Battery

The battery is housed in the battery bay On the rtght hand side of the car immediately to the rear of the front wing. Its positive tC"mina! is earthed. while the negative term i,,,. I is connected direct toone terminal of the starter solenoid. The main feed is taken from the sante solenoid terminal to the cnd r:erminal of the main terminal


junction block within the battery bay. See Fig.189.

Three different types of opening and loc king arrange_ menu are incorporated for the v ~rance doonl,

Spot Lamp

Early type cars.

Late r type cars,

This lamp is mounted centrally in the radiator air intake aperture and ia controlled by a Push/Pull switeh (Marked '5').

Inspection Lamp

The 'Minalite' type lamp ia housed in the right hand side bulkhead compartment beneath the bonnet. When the lamp ia connected to the inspection lamp/trickle charger socke t the base becomes magnetised and the lamp will therefore adhere to any ferrous metal surface.


This electrical supply/feed socket see Fig. 201 is in direct electrical contact with the battery, c urrent can be drawn rrom the battery, or supplied to it from a trickle charger .

Dipper Switch

This swi t ch is mounted on the roe board and when depressed will raise or dip the head lamp beam, a r ed warning light coming into operation when the main beam is in circuit.

Care of the Battery

Alwaya keep rhe top of rhe balte r y cle an and dry. S mear the cable termi nals with pctro lc \lm jell y toprevem corr or;c ion. Pe rIod ica lly a c hec k s hou ld be carried OUl on the level of the e lect r olyte in each cel l. The ratc of evapor31ion of t he elect r olyte varies according [0 rhe use of the hattery IInd the temperature in which it is ope rating. Never usc a naked light ove r cells , since the gas is explosive . If 'topping up' is req'-l ired, use only pure dhnilled WilIer whi ch must not contact metal (metal fun,>!:l or cnntainer). The tops of the plates should just be covered . Do not over fill since this will cause a viole nt disc hsrge of gas when the battery is being charged by the dynamo n:{!luiting in damage to the surrounding metal wor k.

Type 405 Cars

Description

The 12 volt electrical system i,. a single wire type circuit ha ving the positive (+) pol e of the banery earthed to the e ngine and boor, see Fig.211for carly type Cars and Fig.212 for later type cars. Current is supplied by a two brush dynamo in conjunction with a voltage regulator (on later type cars combined currem/voltage regu lator) and an automatic cut out. Two 35 Amp. fuses are fitted in the accessories circuit.

Dynamo

The dynamo ia belt driven and is mounted in a swivelling cradle on the left hand side of the engine and cooled by a fan at the rear of the dynamo.

Starter Motor

The "tarter motor (located on right hand side of the engine) is of normal design with a 'Bendix' type inertia pinion on a worm shaft to e ngage the flywheel teeth. The direction of rotation is counter clockwise when viewed from the from of the car. Control of the starter motor is via the remote "olenoid switch mounted on the right hand side of the bulkhead.

Voltage Regulator and Fuse Box

The voltage regulator (later cars combined currentl voltage regulator) a nd cut out are housed on a common base !covered by a Single cover! mounted on the electrical control panel in the battery bay, see Fig.213. The main electrical connections are mounted on the base adjacent to the cover. Two fuses {indicated by the markings ('Aux and Aux Ign') arc contained on a block mounted immediately below the regulator. These fuses protect certain acce!lsories as follows:

lndependant of Controlled by Fuse. Ignition Switch. Ignition Switch None. Clock. Head. Side Ignition Circuit and

Tail. Number Plate Warning Li~ht. Lamps. Headlamp Starter Pus Button. Warnin~ L1iht. Panel at Map ca ing Lamps. Boot Lamp (early type cars).

Aux.lgn. Brake Stop. Petrol Gauge. Flasher Indicator... Fla"her Indicator Warning Light, Windscreen Wiper Motor. Petrol Reserve Warning Lamp Reversi;1, Lamp, Demist otor.

Aux. Horns , Interior Light. inspection at Trickle Charger Socket. Fog, &. Spot Lamp. Boot Lamp. (later cars).

Fill:. 213. Voltage r"guiator and fuse box

The regulator controls the output of the dynamo according to the load on the battery and it" state of charge . When the battery is in a low state , the dynamo output is high.

No adjustment to the regulator or Cut out is normally reqUired should however any adjustment become neCess_ ary it !lhould be entrusted to a recognised Lucas agent.

Battery

The battery is housed in the battery bay Oil the right hand side of the car immediately to the rear of the front wing. Its poaitive terminal is earthed while the negative terminal is connected direct to onc te rminal of the starter .. olenoid. The main feed is taken from the same solenoid terminal to the end terminal junction box within the battery bay.

To open the valance door sce Fig.192. Release the toggle fastener on the underside of the panel. Lift the safety catch at the rear and rai!le the door until supported.

Ammeter

The ammeter i .. positioned on the dashboard and is in circuit with all electrical accessories e~cept the starter motor and horn relay.

Brake Lamp Switch

The pressure operated switch is incorporated in the delivery connection of the masrer cylinder as derailed in Brake System of this manual. On left hand drive cars the ..witch is incorporated in the feed to the L.H. from brake imm",diately behind the wheel bay.

Reverse Lamp Switch

" The revers", lamp switch is mounted on the right hand

side of the gearbox, is oftheplungertype and is operated by the reverse gear selector mechanism,


Overdrive Switch (Gearbox Operated) The overdrive swhch is mounted 0f'I the gear 1.0,. lOp
