6.7 Engine/Generator Components
Hazardous voltage.
Can cause severe injury or death.
Operate the generator set only when
all guards and electrical enclosures
areinplace.
Moving rotor.
WARNING
Short circuits. Hazardous voltage/current can cause
severe injury or death. Short circuits can cause bodily injury
and/or equipment damage. Do not contact electrical
connections with tools or jewelry while making adjustments or
repairs. Remove all jewelry before servicing the equipment.
6.7.1 Gas Valve Operation Check
Use the following procedure to check the operation of
the gas valve.
Gas Valve Operation Test Procedure
1. Disconnect the positive (+) lead from the gas valve
terminal.
2. Apply 12 VDC to the gas valve terminal and listen
for an audible click, indicating that the valve
actuates.
3. Replace the gas valve if it does not actuate in
step 2.
6.7.2 Voltage Checks
The wiring harness and some engine/generator
components can be checked with the generator set
battery connected. See Figure 6-14. Place the
controller master switch in the prescribed position and
use a voltmeter to check for voltage at each component.
This verifies that the switches function and that voltage
is present at each component.
6.7.3 Continuity Checks
To further check generator set components, disconnect
the battery and remove wiring harness plugs from the
controller circuit board. Use an ohmmeter to check the
continuity of the components listed in Figure 6-15. Also
see Section 9, Wiring Diagrams.
Figure 6-15 gives resistance readings for functional
components. A zero reading on the ohmmeter indicates
continuity. No ohmmeter reading indicates very high
resistance or an open circuit. A measurement that
varies significantly from the value shown in the table
indicates a faulty component; replace faulty
components.
Note: Disconnect the generator set battery before
performing continuity checks to prevent damage
to the ohmmeter.
