(Fault Code_7) High Temperature - Briggs & Stratton 076000NG Service & Troubleshooting Manual

(FC_7)
HIGH TEMPERATURE
The contacts of the Over Temperature Switch
(OTS) are normally open. If the engine coolant
reaches a critical temperature, the switch
contacts will close and complete a circuit to
ground through Wire # 95.
If the system control panel senses this ground, it
will shut down the generator. The digital display
will show FC_7 and the remote LED will
2
repeatedly flash seven times with a pause.
Common causes for high temperature include:
• Running the unit with the side doors
removed
• Obstructed air inlet or exhaust port
• Debris in the radiator cooling fins
• Loose fan belt
• Low coolant level
Contact Power Solutions, Inc. (PSI Technical
Service Specialists, 1-888-3311-5764 or at:
Serice@PowerGreatLakes.com) for overheating
caused by an engine component, such as a
leaking gasket, water pump, or a faulty
thermostat.
Inspect for and correct any of these conditions
before checking the OTS. Once the problem is
corrected, reset the fault code detection system.

TEST 1 - Check Over-Temperature Switch
1. Turn SYSTEM switch to OFF.
2. Remove the 15 Amp fuse from the system
control panel.
3. Remove Wire #95 (A) from the OTS.
Make sure the wire does not touch the
ground.
4. With the engine at room temperature test
for continuity of the switch (Figure 58).
Figure 58
• If no continuity is measured, the switch
is good. Proceed to TEST 2 - Check
Wire #95.
• If continuity is found, replace the OTS.
5. Reconnect the wiring, install fuse and
reset the exercise timer.
SEE RESETTING THE EXERCISE TIMER ON
