What to do if my Kohler 14/20RES has no AC output?
If your Kohler Portable Generator has no AC output, first ensure the AC circuit breaker is in the ON position. If it trips, reduce the load. If it continues tripping due to a short circuit, contact an authorized distributor/dealer for service. Also, check and reset the auxiliary winding circuit breaker, but if it repeatedly trips, seek professional assistance.
Why does my Kohler Portable Generator stop suddenly?
If your Kohler Portable Generator stops suddenly, check the oil level and look for leaks, ensure you have enough fuel, and reset the controller if it's an overcrank or overspeed shutdown. Also, verify the generator set master switch is in the correct position (RUN or AUTO) and check the remote switch position. If these steps don't resolve the issue, it could be due to a blown controller fuse (F3), in which case you should replace the fuse. If the fuse blows again, or if you suspect an engine malfunction or repeated tripping of the auxiliary winding circuit breaker, contact an authorized distributor/dealer.
What to do if my Kohler Portable Generator does not crank?
If your Kohler Portable Generator doesn't crank, check the controller display for a fault code. Ensure the battery isn't weak or dead by checking power to the battery charger and recharging or replacing the battery if necessary. Inspect battery connections for reversals or poor contact. Also, check and replace fuses F2, F3, and the battery charger fuse if blown, contacting a dealer if they repeatedly blow. Finally, ensure the controller isn't OFF by setting it to AUTO for remote start or RUN for local start.
Why does my Kohler 14/20RES Portable Generator crank but not start?
If your Kohler Portable Generator cranks but doesn't start, starts hard, lacks power, or operates erratically, start by cleaning or replacing the air cleaner. Check the battery and its connections, ensuring they are clean and tight. Inspect the spark plug wires. Also, check the oil level and ensure sufficient fuel pressure. If problems persist, contact an authorized distributor/dealer, as there may be an engine malfunction.
How to fix a Kohler 14/20RES with controller LED display off?
If the controller LED display on your Kohler Portable Generator is off, first ensure the controller is not OFF by pressing RUN to start the generator or AUTO for automatic operation. If that doesn't work, check the controller fuse (F3) and replace it if blown. If it blows again, contact an authorized distributor/dealer. Lastly, check the battery connections and ensure there is sufficient battery voltage, inspecting both the engine starting battery and battery charger.
Why does the red LED stay on for more than 24 hours on my Kohler 14/20RES?
If the red LED stays on for more than 24 hours on your Kohler Portable Generator, load test the battery and replace it if necessary, as it may have damaged cells. If that's not the case, remove any DC overload or short that may be causing the battery charger to reduce its output voltage. You can identify this by disconnecting the battery charger’s black (NEGATIVE) ring terminal from the battery and reapplying AC power, where only the green LED should light. Also, turn off all DC equipment while charging, as onboard DC systems might be drawing too much current.
What causes low output voltage on a Kohler 14/20RES Portable Generator?
If your Kohler Portable Generator experiences low output or excessive voltage drop, the generator set may be overloaded. Reduce the load to resolve this issue.
Why are the red and green LEDs on for more than 24 hours on my Kohler 14/20RES?
If both the red and green LEDs stay on for more than 24 hours on your Kohler Portable Generator, turn off all DC equipment while charging, as onboard DC systems might be drawing between 1.5 and 5 amps. Also, load test the battery and replace it if necessary, as it may have damaged cells. Check that the AC voltage at the battery charger is not extremely low; if it is, apply a higher AC voltage source or reduce the length of the extension cord.
Why does the green LED stay on when the battery is low on my Kohler 14/20RES?
If the green LED stays on when the battery is known to be low on your Kohler Portable Generator, replace the AGS-10 fuse if it's open. Also, clean, tighten, or repair all terminal connections if they are faulty or contaminated. Load test the battery and replace it if necessary, as it may have damaged cells.
