Kohler SB-616 Shutdown Test Box
Designed to aid in shutdown testing on Kohler generators in accordance with Service Bulletin SB-616. The test box provides a convenient, repeatable way to perform pre-low / low oil pressure and high / low coolant temperature shutdown testing during service and diagnostic procedures.

SB-616 Shutdown Testing
Built specifically to aid with the oil-pressure and coolant-temperature shutdown checks called for by Kohler Service Bulletin SB-616.
Common Sensor Connections
Includes connector pigtails for common 2-wire and 3-wire sensor connections to simplify hookup during testing.
Universal Test Lead
A universal alligator-clip pigtail is included for applications where a direct sensor connector cannot be used.
Included sensor/test leads & crossover cable
Each test box includes four removable pigtail leads for common generator sensor/test connections, plus a dedicated red crossover cable used with Test Methods 4 and 5.
Pressure-Sensor Pigtail
Ballenger CONN-85963 pressure-sensor pigtail for compatible generator pressure-sensor connections.
2-Way GT150 Pigtail
Ballenger CONN-85646 2-way GT150 pigtail for compatible 2-wire sensor connections.
EV1 Sensor Pigtail
EV1-style sensor pigtail for compatible generator sensor connections.
Universal Alligator-Clip Pigtail
Universal test lead using Mueller BU-55 and BU-60 alligator clips for applications where a direct sensor connector is not used.
Red Crossover Cable — Methods 4 & 5
Dedicated red crossover lead for SB-616 Test Methods 4 and 5. The matching test numbers on the box face are printed in red as a quick visual reminder to use this cable for those two procedures.
Specific test methods supported by this box
The controls, included pigtails and dedicated crossover lead are configured to support the applicable oil-pressure and coolant-temperature fault simulations used in SB-616 Test Methods 2, 3, 4, 5, 16 and 17.
Combined Sensor Fault Simulation
Uses the 5 kΩ control to simulate applicable sensor resistance changes in the SB-616 coolant-temperature / oil-pressure test arrangement.
500 Ω Coolant Temperature Test
Uses the 500 Ω control to simulate coolant-temperature sensor resistance and verify the applicable warning or shutdown response.
5 kΩ Oil Pressure Test
Uses the 5 kΩ control to simulate oil-pressure sensor resistance and verify the applicable low-oil-pressure fault or shutdown response. Use the included red crossover cable for this test.
Resistor-Network Coolant Temperature Test
Uses the 5 kΩ control together with the required 47 Ω and 22 kΩ resistor network to simulate the applicable coolant-temperature fault conditions. Use the included red crossover cable for this test.
500 Ω Low Oil Pressure Test
Uses the 500 Ω control between the sensor lead and engine-block ground to simulate a low-oil-pressure fault until the generator reaches its shutdown response.
High / Low Coolant Temperature Test
Uses the 5 kΩ control in both directions: one direction to simulate high coolant temperature through shutdown, and the opposite direction to produce the low-coolant-temperature fault.
