The distance between the sensor and the diesel generator flywheel is too far or too close (generally this distance is approximately 2.5 + 0.3 mm). If the distance is too far, it may not be able to sense the signal. If it is too close, it may damage the working surface of the sensor. Due to the high-speed operation of the flywheel, radial (or axial) turbulence occurs. The distance is too close to pose a great threat to the safety of the sensor. It has been found that several working faces of the probe have been scratched. According to practical experience, the distance is generally about 2mm, which can be measured with a feeler gauge.

How to clear code 29 on Onan generator 4KY FA26100j. It won't do anything except blink the light

Have you measured the actual DC voltage on the wires at the genset? If the actual voltage is in the 12.6-13.6dcv range, then the sensor in the genset is bad. If the voltage is indeed high, yu need to find out why.

Honda EM5000SX generator - will not idle up when a load is placed on. Will produce power but will not idle up.

from your description and what you do , the problem is in the auto control unit
it will be in the system to reduce the rpm to idle when there is no load ( auto mains on off controller switching between genset and mains supply)
by turning the auto operation off you are committing the gen set to full rpms regardless of the power requirement
you have the option of having it fixed at an gen set repair shop or leaving it off and starting the genset only when you have a mains power outage
check with an electrician to ensure that it is possible to run it that way as if the mains power unit is not correct , when you start it and you still have mains power , it will destroy the gen set

    Its 230kvaperkins generator it starts normally,but after thirty minutes it shuts dawn automatically indicating low frequency

    Low frequency means the RPM of the motor has fallen off.

    Check your fuel is NOT contaminated or fuel filters plugged.

    Further tests should focus on the govenor system. Possibly it fails when engine gets hot. the frequency is directly proportional to the engine speed.
