 Stop the engine after warming up, and
take out spark plug.
 Install the special tool (compression
gauge adapter) at the spark plug hole
and connect the compression pressure
gauge there.
 Condition : Coolant temperature 20 ° C
and engine speed 200 rpm.
2.3.24. Battery
 Inspect for any leakage of electrolytic solution owing to battery crack, and replace the ba tery in
case
of poor condition.
 Inspect for amount of electrolytic solution, and replenish if insufficient.
 Measure the gravity of electrolytic solution, if less than specif ied value (1.12 ~ 1.28), replenish.
