Important Notes

• Verify part number 545090601 before ordering
• Confirm compatibility with your specific Husqvarna equipment model, engine, flywheel, and ignition-system configuration
• The supplied product information identifies this component as a Phelon Ignition Module
• The exact equipment models and engine applications associated with this ignition module are not identified in the supplied product information
• Do not assume this module is specifically for a chainsaw, trimmer, blower, brush cutter, lawn mower, edger, tiller, cultivator, or other particular equipment type unless confirmed by the applicable Husqvarna parts information
• The exact electrical specifications, ignition timing characteristics, resistance values, mounting dimensions, air-gap specification, connector configuration, and operating parameters are not identified
• Do not assume compatibility with another ignition module based solely on physical appearance, mounting-hole spacing, connector style, or the Phelon designation
• Similar-looking ignition modules can differ in electrical characteristics, timing configuration, mounting position, lead arrangement, connector design, and engine compatibility
• Compare the original module's part number, overall shape, mounting points, electrical leads, connectors, spark plug lead configuration, and installed orientation
• Inspect the associated spark plug, spark plug boot, ignition lead, flywheel, flywheel magnets, wiring, stop-switch circuit, connectors, grounds, and mounting hardware for wear or damage
• A no-spark, weak-spark, intermittent-spark, hard-starting, or engine-stalling condition does not automatically indicate a defective ignition module
• Before replacing the module, inspect the ignition system for damaged wiring, poor grounds, defective switches, incorrect spark plug condition, loose connections, or other electrical faults
• Check the flywheel and applicable magnetic surfaces for damage, contamination, excessive corrosion, or other conditions that may affect ignition-system operation
• Maintain the correct ignition module-to-flywheel air gap specified for the applicable engine during installation
• An incorrect air gap may contribute to weak spark, no spark, component contact, difficult starting, or improper engine operation
• Ensure all mounting surfaces and electrical ground points are clean, correctly positioned, and securely fastened
• Route ignition wires and electrical leads according to the original configuration and keep them away from hot surfaces, sharp edges, and moving components
• Do not drill, grind, cut, solder, splice, reshape, alter mounting holes, modify electrical components, or otherwise alter the ignition module to force compatibility
• Do not bypass or defeat any engine-stop circuit, safety switch, interlock, or other safety-related electrical system
• This listing is for the Phelon ignition module; do not assume that the spark plug, flywheel, ignition switch, wiring harness, connectors, mounting hardware, spark plug boot, or other associated ignition components are included unless specifically stated
• Shut off the equipment, allow the engine to cool, and disconnect the applicable spark plug, battery, or other power source before servicing the ignition system
• Use caution when testing ignition systems, as ignition components can generate high voltage
• After installation, verify proper module mounting, air gap, wiring routing, electrical connections, spark generation, engine starting, idle, acceleration, and overall engine operation before returning the equipment to normal service.
