To remove
(Figure 17)
1. Remove the bezel, glass and bulb.
2. Withdraw the lamp body and disconnect the leads.
Replace in reverse order.
Interior lamp
The interior lamp is located above the rear view mirror and has an
integral light switch within the unit. The light is also operated by a
"courtesy" switch on the drivers' door (both doors on later cars).
Removal of the bulb is facilitated by the removal of the lamp lens.
Gently squeezing the sides of the lens releases the clips to enable the
lens to be removed.
To remove
1. Disconnect the battery (The interior lamp is permanently
live). Remove the lamp lens.
2. Remove two screws, withdraw the lamp assembly and
disconnect from the wiring harness.

spark plugs, horn, windscreen wiper motor, instruments and switches

Battery
The battery is a 12 volt negative earth wet cell lead acid type and is
mounted in a well in the left-hand side of the engine compartment. A
metal strap connected to two hook bolts secured by wing nuts holds
the battery firmly in place
(Figure 19)
.
General maintenance
Keep the battery terminals tight and clean. A smear of petroleum jelly
over the terminals will keep them free from corrosion and protect the
battery posts. Regularly check the electrolyte level in the cells and if
necessary top up with distilled or de-ionised water to bring the level
up to the recommended level. This is just above the separator plates,
visible through the battery cap orifices. The need for frequent topping
up must be investigated, for example the electrolyte may be "boiling
off" because the battery is being over charged by the alternator, in
which case the alternator regulator needs to be checked
(page 112)
.
If one cell needs topping up more than the others carefully inspect the
battery casing for cracking. If damage is found the only solution is to
replace the battery.
The efficiency of the battery can be checked using a hydrometer to
test the specific gravity of the electrolyte. The specific gravity readings
are as follows:
1.280-1.300 - fully charged
1.200 (approx) - half charged
1.150 - fully discharged
If electrolyte has been spilled at any time from any of the cells, check
the specific gravity of the remaining cells and then top-up with
sulphuric acid solution to the same specific gravity value. Always add
the acid to water when mixing the electrolyte, never the other way
round.
It can be extremely dangerous to add water to concentrated
acid.
Never use a naked flame when examining the battery. The fumes
given off are highly flammable and can cause an explosion.
To remove the battery
1. Disconnect the positive and negative leads from the
battery.
2. Unscrew the two wing nuts securing the battery retaining
strap and remove it and the rubber insulation.
3. Lift the battery carefully out of the vehicle, keeping it
upright to avoid spilling any electrolyte.
Replace in the reverse order and ensure that the negative is
connected to earth on reconnection.
High rate discharge test
The high rate of heavy discharge test is carried out as a timed on-load
voltage check usually applied to each of the six battery cells in turn.
Before testing, the battery must have been off charge for several
hours and each cell should be at least 70% charged. The correct "drop
tester" should be rated at 150 to 160 amps.
It is vital to use only a
correctly rated tester.
A cell in good condition should sustain 1.2 to 1.5 volts under test for
10 seconds when the prongs of the tester are held across the
terminals. A weak cell will show a rapidly declining voltage. If all the
cells appear weak, it might be that the battery is still sound, just
discharged. Weakness of any cell requires the battery be renewed.
Battery voltage
By means of the test already described, the condition of the battery
has been ascertained and also its state of charge. The working voltage
should then be checked.
Connect a volt meter between the positive and negative terminals and
note the reading. The minimum reading for a 12 volt battery should
not fall below 10.5 volts. If the voltage does drop rapidly below this
figure the battery should be renewed.
