Product Overview
An engine that loses spark when hot, stalls without fuel starvation, or has no spark with good coils and wiring may have a failed ignitor. These modules are often blamed before the safety circuit is tested.
For the repair to hold up, the part still has to match the original application. This electronic module controls ignition timing on compatible Deere equipment using select Kawasaki and Yanmar engines. Match the connector, mounting, engine code, and original number.
Key Features & Performance
- Electronic ignition timing control
- Plug-in connector design
- Vibration-resistant enclosed housing
- Restores spark control when the original module is confirmed faulty
