How to troubleshoot a Kohler Marine Equipment generator that does not crank?
If your Kohler Marine Equipment generator set doesn't crank, several issues could be the cause. It might be due to a weak or dead battery, so try recharging or replacing it. Also, check the battery connections to ensure they are not reversed or poorly connected. Inspect the engine and controller connections for any looseness and check the wire harness continuity. Furthermore, examine fuses F2 on the controller and RIB, replacing them if blown. For the crank relay on the RIB, verify connections and check for 12VDC on lead 71N. Check the connections to the master switch on the ADC 2100, as well as the starter connections. Finally, check the controller connections and operation, ensuring power is supplied to the controller. Also, verify the line circuit if the F3 fuse is blown, check voltage ...
What causes no output voltage in my Kohler 4EFCD-Low CO?
If your Kohler Marine Equipment has no output voltage, check if the AC output circuit breaker is open. Verify AC voltage on the generator side of the circuit breaker. If voltage is present, the issue may be a tripped breaker due to a problem in the load circuits. Perform a separate excitation procedure to determine if the problem lies within the alternator or the control system. Check the continuity of wiring, terminals, or pins in the buildup circuit or SCR module circuit. Inspect the brushes and replace them if they are worn.
