6) Install ignition coil assemblies referring to “Ignition Coil
Assembly” in this section.
7) Install high-tension cords securely by gripping their caps.
Ignition Coil Assembly (Including Ignitor)
1) Disconnect negative cable at battery.
2) Remove cylinder head upper cover.
3) Disconnect ignition coil connector.
4) Disconnect high-tension cord (3) from ignition coil assembly
(2).
5) Remove ignition coil bolts (1) and then pull out ignition coil
assembly. NOTE:
NGK IFR5E11 or DENSO SK16PR-A11 is highly recom-
mended for better engine starting performance under –
25°C (– 13°F).
CAUTION:
When servicing the iridium/platinum spark plugs (slender
center electrode type plugs), do not touch the center
electrode to avoid damage to it. The electrode is not
strong enough against mechanical force as it is slender
and its material is not mechanically tough.

General Description
Battery
The battery has three major functions in the electrical system.
It is a source of electrical energy for cranking the engine.
It acts as a voltage stabilizer for the electrical system.
It can, for a limited time, provide energy when the electrical
load exceeds the output of the generator.
CARRIER AND HOLD-DOWN
The battery carrier should be in good condition so that it will sup-
port the battery securely and keep it level.
Before installing the battery, the battery carrier and hold-down
clamp should be clean and free from corrosion and make certain
there are no parts in carrier.
To prevent the battery from shaking in its carrier, the hold-down
bolts should be tight enough but not over-tightened.
ELECTROLYTE FREEZING
The freezing point of electrolyte depends on its specific gravity.
Since freezing may ruin a battery, it should be protected against
freezing by keeping it in a fully charged condition. If a battery is
frozen accidentally, it should not be charged until it is warmed.
SULFATION
If the battery is allowed to stand for a long period in discharged
condition, the lead sulfate becomes converted into a hard, crystal-
line substance, which will not easily turn back to the active mate-
rial again during the subsequent recharging. “Sulfation” means
the result as well as the process of that reaction.
Such a battery can be revived by very slow charging and may be
restored to usable condition but its capacity is lower than before.
