Questions And Answers Of The Customers

What is the specific role of the 18*1.5/70A speed sensor in the SA423G1 generator set?

The 18*1.5/70A is a Magnetic Pickup (MPU) sensor. It monitors the rotational speed of the engine flywheel by detecting the passing teeth of the ring gear. It sends an AC voltage signal to the Engine Control Unit (ECU) or governor, which then adjusts the fuel supply to maintain the precise 50Hz or 60Hz frequency required by the generator.
Why should I use a genuine 18*1.5/70A0A instead of a cheap aftermarket alternative?

The 18*1.5/70A is calibrated for specific induction characteristics. Aftermarket sensors may have different internal resistance or magnet strengths, which can lead to "lazy" governor response times. This results in poor voltage regulation when the generator is subjected to sudden block-load changes.
How do I troubleshoot an "Erratic Speed" or "Hunting" (RPM fluctuation) issue related to this sensor?

First, check for signal noise. Inspect the wiring from the sensor to the controller to ensure there are no frayed wires or loose connectors. Second, verify the physical air gap between the sensor tip and the flywheel teeth. If the signal is "dirty," the controller will struggle to maintain steady RPM, resulting in visible engine surging.
