CAUTION
Be careful while handling

cidental contact with the heated plug tip could
cause personal in ury. j
1. Disconnect the wire lead(s) to the glow plug.
2. Remove the glow plug.
3. Inspect the glow plug for signs of a burnt glow plug
end tube.
NOTE: If the metal of the glow plug end is melted, it is
a sign of cylinder overheating.
4. Connect the positive (+) battery terminal to the glow
plug terminal, and the negative (–) battery terminal to
the plug body (Fig. 34). If the glow plug glows red-hot in
9 to 12 seconds, the glow plug is operating correctly. DO
NOT leave on more than 20 seconds.
5. Replace any glow plugs that do not operate correctly.
