How to troubleshoot inadequate fuel supply in 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. Check the fuel supply pressure to the generator set.
How to fix no AC output on my Kohler 20RESA?
If your Kohler Portable Generator has no AC output, check if the line circuit breaker is in the OFF position and switch it to the ON position. Also, reduce the load on the generator if the circuit breaker is tripping due to an overload. If the line circuit breaker is tripping because of a short circuit or if the auxiliary winding circuit breaker tripped, contact an authorized Kohler distributor/dealer for service. If the auxiliary winding circuit breaker trips repeatedly after you reset it (it is located in the controller’s service access area), contact an authorized Kohler distributor/dealer for service.
What to do if my Kohler 20RESA Portable Generator cranks but won't start?
If your Kohler Portable Generator cranks but doesn't start, starts hard, lacks power, or operates erratically, try the following: * Clean and/or replace the air cleaner. * Recharge or replace the battery if it's weak or dead. * Clean and tighten the battery connections if they are poor. * Check the spark plug wires to ensure they are properly connected. * Check for oil leaks and add oil if the level is low. * Check the fuel supply and valves to ensure sufficient fuel pressure. If these steps don't resolve the issue, contact an authorized Kohler distributor/dealer, as it may indicate an engine malfunction.
How to troubleshoot a Kohler 20RESA that won't crank?
If your Kohler Portable Generator doesn't crank, the following could be the reasons: * A weak or dead battery: Recharge or replace the battery. * Reversed or poor battery connections: Check the connections. * A fault shutdown: Check the controller display for fault messages, correct the fault condition, and reset the controller. * The generator set being in the OFF mode: Press the RUN button to start the engine or press AUTO to allow remote starting.
What causes low output voltage on my Kohler 20RESA Portable Generator?
Low output or excessive voltage drop in your Kohler Portable Generator is often caused by the generator set being overloaded. Reduce the load to resolve this issue.
Why is the controller display off on my Kohler 20RESA Portable Generator?
The controller display on your Kohler Portable Generator might be off due to low or no battery voltage. Check the connections and the generator set battery.
Why is the backlight off on my Kohler Portable Generator's controller display?
The backlight on the controller display of your Kohler Portable Generator turns off after about 1 minute of inactivity. The backlight will turn on when a button is pressed or the generator set starts.
What to do if the breaker will not close in RUN on my Kohler 20RESA Portable Generator?
If the breaker won't close in RUN on your Kohler Portable Generator, it could be due to: another breaker being closed (stop the other generator set), auto-discovery not being complete (initiate auto-discovery by ensuring this generator is in RUN mode and the other is stopped with the controller in OFF mode), or bus sensing not being connected correctly (check wiring between both generators and the Automatic Paralleling Module).
Why does SiteTech indicate that both engines are under load, but the ATS has not transferred on my Kohler 20RESA Portable Generator?
If SiteTech indicates that both engines are under load but the ATS hasn't transferred on your Kohler Portable Generator, it could be due to the metering on either generator being backwards. To fix this, select a different model number for the affected generator, then re-select the correct model number. This clears the CT direction flag and allows the generators to re-determine CT direction.
Why does my Kohler Portable Generator experience Main Power Overload Shutdown?
The Main Power Overload Shutdown is caused by an overcurrent condition on the DC power supply circuit. Check the crank, run, and flash relay circuits for short circuits. To address nuisance shutdowns, update the controller firmware to version 6.7 or higher.
