FAQ

Q: How can I confirm this 3050692 starter relay fits my engine?
A: First, verify your current part number. If it is 3050692, this unit is a direct replacement. Second, check your engine model. This is the standard relay for the NTA855 and is very commonly used on KTA19, KTA38, KTA50, M11, VTA28, and N14 engines. If your engine is different, please contact us with your engine serial number for verification.

Q: What is the difference between a starter relay and a magnetic switch?
A: In this context, they are the same component. The part (3050692) functions as a heavy-duty solenoid. It uses a small electrical current from the ignition switch to close a high-current circuit for the starter motor. On many engines, this same part also operates the fuel shutoff (flameout) mechanism, cutting the fuel supply to stop the engine.

Q: What are common signs of a failing starter relay?
A: Symptoms include the engine not cranking (starter not engaging), a clicking sound from the relay without the starter turning, intermittent starting issues, or the engine failing to shut off when the key is turned off. If the relay fails to open the fuel shutoff circuit, the engine may continue to run even with the key off. Replacing a faulty relay with this genuine 3050692 part will resolve these issues.
