Continued
Problem Possible Cause Remedy
Genset will not pull load Incorrect Engine Speed
Load not connected properly
Load too large for unit
Remove electrical load, output should be 61−62 Hertz adjust engine
speed if necessary.
Verify voltage at the load and the connections to the proper
receptacle or load terminal block.
Verify load amperage is less than the generator set rated.
Note: For inductive loads, use the starting amperage rating of the
load (not the running amperage rating). Starting amps may be as
much as 5 times the running amps.
Electrical shock when frame is
touched Static charge.
Grounded armature or field coil. Ground generator frame at local reference ground (see Section 3).
Contact service center.
Mechanical noise (alternator) Defective bearing
Rotor rubbing on stator
Loose or misaligned coupling
Replace bearing.
Bad bearing − replace.
Bent shaft − contact service center.
Loose end bell − tighten;
Loose drive Discs − tighten
Tighten; align coupling and alternator shaft to engine shaft.
Trailer lights inoperable Trailer to tow vehicle connection
Trailer electrical connection not compatible
Insufficient Ground connection
Faulty light bulb
Connect trailer lighting connector to tow vehicle trailering connector
Use adapter plug to convert from connector style found on trailer to
connector style found on tow vehicle or replace connector with com-
patible mate
Verify there is a ground wire connection from the tow vehicle to the
trailer. Do not rely on the trailer tow coupling for the battery ground
connection. Repair as necessary.
Replace as necessary
Trailer sways during towing Tow vehicle trailering ratings too small
Trailer tongue not level on tow vehicle
Towing at excessive speed
Check tow vehicle ratings meet or exceed the Gross Vehicle Weight
Rating (GVWR) of the trailer. Use larger tow vehicle as necessary.
Seek expert advise.
Adjust trailer or tow vehicle as necessary for trailer tong to be level
or slightly higher than rear of tow vehicle when additional supports
have been removed. View and make adjustments while vehicle and
trailer are on level surface. Seek expert advise.
Reduce tow vehicle speed and use caution while braking. Obey all
local laws and regulations, never exceed the posted speed limit,
and use reasonable care when towing any type of trailer.
Contact local authority having jurisdiction.
Note: After the engine is stopped, there is a 15 second restart delay before engine cranking.
Fault Shutdowns Under certain operating conditions, onboard sensors determine that a condition may cause
damage if operation continues. The onboard controller is programmed to sound an alarm or
immediately stop (shutdown) the generator. These conditions are as follows:
1. An alarm fault is indicated by an alarm light located on the operator panel:
a.
Overspeed − indicates the engine governor allowed speed to exceed safe limits.
b. Overcrank − indicates engine failed to start within programmed time period.
c. Low Oil Pressure − Safe engine operating oil pressure was not maintained.
d. Overtemperature − indicates safe operating coolant temperature was exceeded.
2. Engine cannot be restarted until the alarm condition is corrected.
3. Reset the alarm condition (after alarm condition is corrected) by pressing “Reset”.
Operation can be attempted, observe the operator panel when operation is resumed to
ensure alarm condition is removed.
Overload When maximum current output exceeds the output breaker limit, the main breaker will trip. When
this occurs, the load must be reduced and the breaker reset before operation can be resumed.
Note: The Main Breaker cannot be reset if load connection box door is open. This door must be
closed before the breaker can be reset to connect the electrical load.
Service & Parts Service and parts for your generator can be obtained from an authorized service center.
Please have the following information available prior to contacting the service center:
The model number and serial number of the generator set.
A complete and accurate description of the part (part number if known).
Note: Engine parts can usually be obtained from a local distributor by using the information in
the engine manufacturer’s owner’s manual.
