• Check for ease of resetting. The service indicator
should reset in less than three pushes.
• Check the movement of the yellow core when the
engine is accelerated to the engine rated speed.
The yellow core should latch approximately at the
greatest vacuum that is attained.
If the service indicator does not reset easily, or if the
yellow core does not latch at the greatest vacuum,
the service indicator should be replaced. If the new
service indicator will not reset, the hole for the service
indicator may be restricted.
The service indicator may need to be replaced
frequently in environments that are severely dusty.

Engine Ground - Inspect/Clean
Inspect the wiring harness for good connections.
Perkins use the starter motor in order to ground the
engine. Check the connection on the starter motor at
every oil change. Ground wires and straps should be
combined at engine grounds. All grounds should be
tight and free of corrosion.
• Clean the grounding stud on the starter motor and
the terminals with a clean cloth.
• If the connections are corroded, clean the
connections with a solution of baking soda and
water.
• Keep the grounding stud and the strap clean and
coated with suitable grease or petroleum jelly.
