5. INSPECTION
Perform a visual inspection of the GCU and inverter. Component inspection is listed in the order in which they need to be removed to
access the next component.
Inverter:
To visually inspect the inverter, remove the front cover and the control panel.
Visually inspect the back of the inverter for any discolored or damaged wiring, capacitors, or
connectors, and note any bubbling, corrosion, or other unusual conditions. If any of these
issues are present, the inverter is likely faulty.
While the inverter may be faulty, it may not be the cause for the overall generator failure.
Some other circumstance, or other component failure, may have caused the inverter to fail.
Test the stator (see
) before contacting Techline or your DSM for further
instruction.
GCU:
With the front cover and the control panel removed, visually
inspect the circuit board on the back side of the GCU for any discolored
spots, deterioration, contamination, or deformed capacitors.
Stator:
The output and resistance tests performed in the Generator
Troubleshooting Guide or the appropriate shop manual should be enough
to determine if the stator is good or not. The stator resistance readings
should be consistent. If there is more than 0.2
Ω
of difference between
readings, the stator has failed.
To visually inspect the stator, remove the spark plug, inverter, and recoil
starter, and then rotate the cooling fan until you can look through the rotor
windows at the stator windings. Rotate the rotor by hand and slowly look
for any signs of overheated or discolored stator windings.
