    What to do if the starter on my Kohler 13.5CCOZ doesn't work?
    • B
      Billy ArnoldSep 10, 2025
      If the starter on your Kohler Inverter isn't working correctly, begin by cleaning and tightening any loose connections. Also, replace the starter solenoid, replace the start/stop switch, and check the wiring.

    What causes low output voltage on a Kohler 13.5CCOZ?
    • C
      Chris DavisAug 22, 2025
      If you're experiencing low output or an excessive voltage drop on your Kohler Inverter, try adjusting the governor if the engine speed is too low. If the generator is overloaded, reduce the load.

    How to fix a Kohler 13.5CCOZ Inverter that won't crank?
    • A
      aunderwoodAug 25, 2025
      If your Kohler Inverter won't crank, possible causes include a weak or dead battery (recharge or replace it), reversed or poor battery connections (check and correct them), a tripped circuit breaker in the controller (reset it), a defective start/stop switch (check and replace if necessary), a defective starter solenoid (check and replace if necessary), or a defective starter (replace/repair as necessary).

    What to do if my Kohler 13.5CCOZ cranks but won't start?
    • S
      Scott ScottAug 26, 2025
      If your Kohler Inverter cranks but doesn't start, check these potential issues: * Make sure you're not out of fuel; if so, replenish it. * Check for any fault shutdowns and examine the shutdown switches. * Ensure the fuel shut-off valve is open. * Other possible causes include a defective fuel feed pump (replace it), a clogged fuel filter (service the filter element), or air in the fuel system (bleed the air). Also, consider water or dirt in the fuel system (drain and flush), incorrect fuel type (use the correct type), incorrect crankcase lube oil (use the correct lube oil), or a faulty fuel solenoid (replace it). Finally, check for a clogged air intake (clean or replace it), a faulty ground connection (clean and retighten), or a weak/dead battery (recharge or replace).

    How do I troubleshoot a Kohler 13.5CCOZ with no AC output?
    • M
      Maria SandersAug 28, 2025
      If your Kohler Inverter has no AC output, verify the following: * Ensure the circuit breaker is in the ON position; if it's OFF, reset it. * If the circuit breaker tripped due to an overload, reduce the load and reset the breaker. * Confirm the ship-to-shore transfer switch is set to generator power, not OFF or SHORE. * Check if the controller circuit breaker has tripped and reset it if necessary.

    Why does my Kohler 13.5CCOZ engine start but not continue running?
    • L
      Lisa MaciasAug 29, 2025
      If your Kohler Inverter engine starts but doesn't continue to run after releasing the start switch, it could be due to no generator output voltage (check AC voltage), a defective low oil pressure (LOP) safety shutdown switch (replace it), or a high temperature shutdown (check coolant level). Also, consider defective high exhaust temp. (HET) and/or high water temp. (HWT) safety shutdown switch(es) and replace them if needed.

    What could be the reason for engine knocking in my Kohler 13.5CCOZ Inverter?
    • M
      melaniealvarezSep 18, 2025
      If your Kohler Inverter's engine is knocking, the cause might be using the incorrect type of fuel (use correct type of fuel) or air in injectors (bleed air).

    What causes low lube oil pressure in a Kohler 13.5CCOZ?
    • P
      Pamela ThomasSep 12, 2025
      Low lube oil pressure in a Kohler Inverter can be caused by a low lube oil level (add lube oil), incorrect lube oil viscosity (drain and fill with correct lube oil), or a defective oil pressure switch (replace safety shutdown switch).

    What causes high fuel consumption in a Kohler Inverter?
    • L
      Lisa PatelSep 8, 2025
      High fuel consumption in your Kohler Inverter could be due to several factors: using the incorrect type of fuel (use correct fuel), a clogged or dirty air intake silencer (service air intake silencer), an overloaded engine (reduce load), or fuel leakage (check for leaks at fuel tank, lines, and engine fuel system). Also, check the thermostat and consider the engine temperature.

    Why is my Kohler Inverter engine operating erratically?
    • S
      Sean DelgadoSep 5, 2025
      If your Kohler Inverter engine operates erratically, consider these potential causes: a clogged air intake (service air intake silencer), stale or bad fuel (replace fuel), a clogged fuel filter (replace fuel filter), an obstructed vent in the fuel tank cap (clean cap in solvent and blow dry), or water, dirt, or air in the fuel system (drain, flush, fill, and bleed air in the system). Also, check the fuel feed pump (replace if defective).
