GLOW PLUGS
A WARNING: These glow plugs will become very hot
·to the touch. Be careful not to burn your fingers when
testing plugs.
To inspect the plug, remove the electrical terminal connections,
then unscrew or unclamp each plug from the cylinder head.
Thoroughly clean each plug's tip and threads with a soft brush
and cleaning solution to remove all the carbon and oil deposits.
While cleaning, examine the tip for wear and
bum erosion; if it
has eroded too much, replace the plug.
An accurate way to test glow plugs is with an ohmmeter.
Touch one prod to the glow plug's wire connection, and the
other to the body
of the glow plug, as shown. A good glow plug
will have a 0.9 ohm resistance. This method can be used with
the plug in or out
of the engine. You can also use an ammeter to
test the power drain (13 amps per plug).
Re-install the plugs in the engine and test them again. The
plugs should get very hot (at the terminal end) within 5 to
10
seconds. If the plugs don't heat up quickly, check for a short
circuit. When reinstalling the glow plugs, use anti-seize
compound on the threads.
A CAUTION: Do not keep giow plug on for more than
30 seconds.
