Compatibility Notice

Frequently Asked Questions
Q: Can bad glow plugs make a good relay seem faulty? A: Yes. Open or shorted plugs, poor bus connections, and low battery voltage can all reduce preheat performance.
Q: Why does the relay click but no power reaches the plugs? A: The control coil may operate while the internal high-current contacts are burned or the cable connection has failed.
Q: How do I confirm fitment before ordering? A: Match the original reference number, equipment model and serial number, dimensions, connector or mounting details, and the product photos. Do not rely on appearance alone.
Q: Is this made by the original equipment manufacturer? A: No. This is a new aftermarket part. Brand names and model numbers are used only to identify compatible equipment.
