GLOW PLUG SWITCH TEST
TEST SWITCH TEST (See Figure 10G-11)
The glow plug switch is pushed by the operator to allow
current flow to the glow plugs, prior to starting the
machine.
See Figure 10G-11 and test switch as follows:
1. Disconnect leads at switch.
2. Set multimeter to 200 Ω (ohms) scale.
3. Connect multimeter test leads to switch terminals
with the switch in the OFF position.
•
There should be no reading on the multimeter.
4. Hold switch in the ON position.
•
There should be a reading of 0–0.5 Ω (ohms)
on the multimeter.
Replace a switch that does not meet all the above
test results or has resistance of 0.5 Ω (ohms) or more.
