3. System Overheating:
System overheating may be caused by re-circulation of hot air through oil cooler,
dirty or obstructed oil cooler fins, restricted hydraulic fluid flow, excessive generator
load, restricted airflow, previously overheated (old) fluid, non-functional fan, or
improperly adjusted pump.
a. Check the oil cooler fins for debris or damage. Clean and/or replace cooler.
b. Verify that the generator load is not excessive.
c. Verify that there is proper ventilation.
d. Verify that the DC fan motor is operating properly.
e. Verify that warm air from the fan outlet is not being re-circulated through the
cooler.
f. Check the hydraulic fluid to see if it is black or darkened. This indicates
overheating or aging. Drain and flush the system.
g. Fill with new, clean hydraulic fluid.
4.
Low Hydraulic Fluid Level In Reservoir:
Low hydraulic fluid level in reservoir can be caused by leaking fittings, hoses or
pipes.
a. Check all the fittings for leaks. Tighten any loose fittings that are found (but do
not over-tighten).
b. Replace defective fittings.
c. Check all tubing for leaks. Repair or replace as necessary.
Electrical Problems
1.
No Output Voltage:
a. No output voltage may be caused by excessive current draw opening the circuit
breakers. (The circuit breakers can be found mounted on the generator wiring
enclosure.) Remove all electrical loads from the generator and reset breaker(s).
Re-engage electrical load in increments. If possible, monitor current draw with
the Command & Control Center to determine which portion of the load is
causing the breaker to open.
b. The PTO will not engage or is faulty. Contact Smart Power

Systems.
c. The generator’s system controller has lost power (reference Figure 2). The
Command & Control Center would stay dark even after the mode and/or on/off
switch is pressed. Verify that the vehicle +12V supply has both +12 volts and
ground. If 12 volts is not available check the vehicle for a blown fuse or a
loose/open electrical connection.
