INSPECT
Inspect fuel lines for damaged connectors and lines.
Inspect 24 VDC power cables for frayed insulation and damaged connectors.
Inspect cloth exhaust ducts for cuts or tears.
Inspect air conditioner vibration mounts for damage or deterioration.
TEST
Fuel Lines: Refer to the troubleshooting procedures in the MBU manual to determine if the
problem with the MBUs is caused by a fuel problem. If the problem is lack of fuel, check the
connections at the fuel source, that the proper fuel is being used, and that the vent valve on the
fuel can adapter is open. Check the fuel line connections at the fuel line tee on the left side of
the Mechanical Room wall behind the generator for any signs of fuel leakage.
24 VDC Electrical Cable: Refer to the troubleshooting procedures in the MBU manual to
determine if the problem with the MBUs is caused by an electrical problem. If there is an
electrical problem, remove a 24 volt connector from any of the MBUs and check for 24 VDC. If
there is no voltage, check the switch position on the MBU Converter (pulled forward position
away from the wall) and the power connector. Remove the 24 VDC power connectors at the
MBU Converter and check for 24 VDC. If the voltage is not 24 VDC, replace the MBU
Converter. See the replacement procedure in the following section.
