FAQ

Q1: How do I verify if this solenoid (3050692) fits my specific starter motor?
A: Please check the part number stamped on your existing solenoid. This replacement matches Cummins numbers 3050692, 5861141126a, and 586-114112-6a. Also, measure the mounting bolt pattern and terminal positions (S, B, M terminals). If your solenoid has a different form factor, it may not be compatible. We recommend consulting your starter motor’s technical manual for confirmation.

Q2: What are the common signs of a failing starter solenoid in a Cummins KTA19 or NTA855 engine?
A: Common symptoms include a single loud click without the engine cranking, intermittent starting (starter works sometimes but not others), or a continuous grinding noise. If the engine does not crank and the battery is known to be good, the solenoid is a primary suspect. Testing the solenoid with a multimeter for continuity between the battery and starter terminals when the ignition is engaged can confirm failure.

Q3: Can this solenoid be used in a marine environment?
A: Yes, it is suitable for marine applications such as workboats and generator sets powered by compatible Cummins engines (e.g., N14, KTA19). However, for extended life in a saltwater environment, we recommend applying a dielectric grease to the electrical connections and ensuring the solenoid is mounted in a protected area away from direct spray. The standard unit is not a fully sealed marine-spec part but performs reliably in engine rooms.
