What to do if the green LED stays on when the battery is known to be low in my Kohler Inverter?
- R
  Randy AndersenAug 7, 2025
  If the green LED on your Kohler Inverter stays on even when the battery is known to be low, it could be due to a few reasons. First, check for an open DC output fuse and replace the AGS-10 fuse if necessary. Second, inspect for faulty or contaminated terminal connections; clean, tighten, or repair all terminal connections. Finally, one or more cells could be damaged, so perform a load test on the battery and replace it if required.

What to do if Kohler Power Supply generator set engine does not crank?

  Gina RubioAug 12, 2025
  If your Kohler Power Supply generator set engine doesn't crank, start by checking the battery connections and ensure they are correctly connected and tightened. A weak or dead battery could also be the culprit, so try recharging or replacing it. Inspect the engine and controller connections for open circuits, tightening any loose connections and replacing damaged harnesses or leads. Finally, check controller fuse F3 and replace it if blown; if it blows again, investigate the circuit and components.

  If you have inadequate fuel supply in your Kohler Power Supply, check for damaged primary or secondary fuel regulators and loose connections to the fuel solenoid valve. Also, inspect the fuel shutoff valve for damage or closure, verify that the LP fuel tank is not empty, and investigate any other potential issues with the fuel supply. Finally, check the fuel supply pressure to the generator set.

What to do if red and green LEDs stay on for more than 24 hours on my Kohler Inverter?
- G
  garrettgutierrezAug 21, 2025
  If both the red and green LEDs on your Kohler Inverter stay on for more than 24 hours, it could be due to several reasons. First, onboard DC systems might be drawing between 1.5 and 5 amps; in this case, turn off all DC equipment while charging. Second, one or more cells could be damaged; you should load test the battery and replace it if necessary. Lastly, there might be extremely low AC voltage at the battery charger; try applying a higher AC voltage source or reducing the length of the extension cord.

What to do if the red LED stays on for more than 24 hours on my Kohler Inverter?
- T
  Timothy TannerAug 27, 2025
  If the red LED on your Kohler Inverter remains on for more than 24 hours, there are a few potential causes. It could be due to one or more inoperative or damaged cells, in which case you should load test the battery and replace it if needed. Alternatively, the battery charger might have reduced its output voltage due to a DC overload or short; remove the source of the overload or short, disconnect the battery charger’s black (NEGATIVE) ring terminal from the battery, reapply AC power, and check if only the green LED lights up. Another possibility is that onboard DC systems are drawing more current than the battery charger can replace, so try turning off all DC equipment while charging.

How to fix no LED lights on my Kohler Inverter when AC power is applied?
- T
  Tammy RobertsonAug 31, 2025
  If neither of the LEDs on your Kohler Inverter turn on when AC power is applied, it could be due to two main reasons. First, there might be no AC power available at the battery charger; connect AC power or reset the AC breaker on the main panel. Second, there could be a component failure, which would require replacing the battery charger.
