What causes inadequate fuel supply in Kohler 8.5RES?
To address an inadequate fuel supply in your Kohler Portable Generator, check for damaged primary or secondary fuel regulators, loose connections to the fuel solenoid valve, a damaged or closed fuel shutoff valve, an empty LP fuel tank, or other problems with the fuel supply.
What to do if my Kohler 8.5RES Portable Generator cranks but does not start?
If your Kohler Portable Generator cranks but doesn't start, first, make sure the manual fuel valve is open and check the fuel supply tank. Insufficient fuel pressure could also be the cause, so verify adequate fuel pressure, considering the generator and other gas appliances. Inspect the fuel regulator/valve and check spark plug wires and connections. Clean, regap, or replace the spark plugs if needed. Finally, check for loose or open connections at the fuel valve and the engine spark control module, ensuring controller/engine wiring continuity.
Why does my Kohler 8.5RES start but then shut down?
If your Kohler Portable Generator starts and then shuts down, check the controller's LED display for a fault shutdown code. Correct the fault, then move the generator set master switch to OFF/RESET to reset the controller. Also, make sure the fuel supply is on and inspect the fuel lines for restrictions or excessive length. Replace a clogged air cleaner element. Check fuses F1, F2, and F3, replacing any that are blown. If a fuse blows again, test the generator components. If the engine is hot, check the air intake, fuel adjustment, oil level, and air inlet/outlet.
How to troubleshoot no output voltage on a Kohler 8.5RES?
If your Kohler Portable Generator has no output voltage, first check if the AC output circuit breaker is open. See if there's AC voltage on the generator side of the breaker. If voltage is present, the issue is likely a tripped breaker due to load circuit problems; check for shorts or overloads on the load side before resetting it. Also, inspect aux winding fuse F1 and replace it if blown. If it blows again, check the stator. Finally, inspect the brushes and replace them if they are worn.
What to do if Kohler Portable Generator does not crank?
If your Kohler Portable Generator doesn't crank, start by recharging or replacing the battery if it's weak or dead. Check the battery charger fuse, power supply, and operation. Inspect battery connections for reversed or poor connections. Look for loose connections or wire harness continuity issues in the engine/controller connections. Replace any blown fuses (F3 on the controller or F2 on the relay interface board). Check connections to the RIB, ensuring 12VDC to the RIB on lead 71N. Check connections to the controller and master switch. Inspect the starter connections. Finally, check the controller connections and operation, ensuring power to the controller, and try moving the generator set master switch to OFF/RESET and then to RUN.
How to fix light flicker on a Kohler Portable Generator?
To address light flicker with your Kohler Portable Generator, check and adjust the voltage stability (gain) setting using the controller keypad.
How to reduce noisy operation of my Kohler 8.5RES Portable Generator?
To address noisy operation in your Kohler Portable Generator, check the exhaust system for leaks and replace components as necessary.
What to do if Kohler Portable Generator cranks but does not start?
If your Kohler Portable Generator cranks but doesn't start, here are a few things you can check: * Ensure the manual fuel valve is open and that there is fuel in the supply tank (if using LP). * Check the fuel pressure to the generator set, ensuring it's adequate for the generator and any other gas appliances. * Examine the fuel regulator/valve operation. * Inspect spark plug wires and connections; replace or clean and regap the spark plugs. * Look for loose or open connections at the fuel valve (lead 70A) and the engine spark control module (leads IGN and 70A). Also, verify the controller/engine wiring continuity.
How to fix Kohler 8.5RES that operates erratically?
If your Kohler Portable Generator is operating erratically, try the following: * Replace the air cleaner element if it's clogged. * Replace and regap the spark plugs. * Replace the spark plug wires. * Connect DSAI leads for natural gas or disconnect for LP (12kW models only). * Check fuel lines for restrictions. * Check and/or adjust the fuel mixture. * Check for loose connections to the mag pickup. * Adjust governor stability. * Test and/or replace ignition system components.
What causes Kohler 8.5RES Portable Generator to overheat?
If your Kohler Portable Generator is overheating, it could be due to: * Inadequate cooling. Inspect the cooling system for air intake obstructions. * Incorrect fuel mixture adjustment. Readjust the fuel mixture. Note: Adjusting the fuel mixture may void the emission certification.
