580BFS Mark Iii, 580BTS Mark III Ignition Coil Replacement Part – Husqvarna

580BFS Mark Iii, 580BTS Mark III Ignition Coil Replacement Part – Husqvarna.

Restore Dependable Starting & Eliminate Thermal Spark Loss: Genuine Husqvarna Coil

Eliminate high-RPM misfires, sudden shutoffs when hot, hard starting, weak spark, and ignition failure on your heavy-duty commercial backpack blower. This Genuine Husqvarna Factory OEM Ignition Coil Module (Part Number 599899501) is the authentic solid-state electronic armature engineered explicitly for Husqvarna 580BFS Mark III and 580BTS Mark III commercial backpack blowers . Operating a high-output 75.6cc commercial engine with an aging or failing ignition coil wastes crew time and leaves commercial cleanup routes unfinished.

Precision-manufactured directly to Husqvarna’s exacting professional forestry and landscape specifications, the 599899501 features high-density insulated copper windings completely sealed within an oil- and heat-resistant epoxy encapsulation shell. This heavy-duty potting protects the internal transistorized circuitry against high ambient engine cowl temperatures and heavy 2-stroke vibration. It arrives complete with the factory-terminated high-tension spark plug lead, heavy-duty insulated spark plug boot, terminal spring clip, and primary stop/kill-switch lead connector, guaranteeing a direct bolt-on installation with factory-calibrated ignition advance timing.

This authentic factory replacement component is cataloged under Husqvarna OEM Part Number 599899501 (599 89 95-01 / 5998995-01 / Ignition Module / Armature, Ignition / 580BTS Mark III Coil / 580BFS Magneto) . (Note: Fitment is serial number dependent on Mark III platforms—verify your model and full serial number prior to purchase).

Why This Genuine Husqvarna 599899501 OEM Ignition Coil is the Pro Standard:

100% Genuine Factory OEM Component: Precision-manufactured directly by Husqvarna for exact laminate stack alignment and factory ignition advance curves.

Solves Heat-Related Cutouts: Eliminates thermal breakdown where the engine dies after 10 to 15 minutes of heavy commercial blowing.

Solid-State Epoxy Encapsulation: Fully seals sensitive electronic components against engine heat, oil residue, moisture, and high-frequency vibration.

Factory-Calibrated Spark Energy: Generates maximum kilovolt output to jump spark gaps under high cylinder compression, ensuring easy first-pull starts.

Complete Plug-and-Play Assembly: Includes the high-voltage plug wire, factory boot, terminal clip, and stop-switch connector for direct bolt-on replacement.

Optimized Fuel Economy & Power: Maintains precise ignition timing across the entire throttle band, preventing unburnt fuel waste and carbon fouling.

🛠️ Pro-Maintenance Tip: Watch the "Business Card Air Gap & Flywheel Rust Secret!" Business Card Air Gap Secret: When bolting the new 599899501 ignition coil onto the engine crankcase, the clearance between the metal coil laminations and the flywheel magnets must be set precisely (typically 0.012" to 0.014" ). To set this without specialized feeler gauges: rotate the flywheel until the built-in magnets are facing away from the coil mounts. Loosely snug the two coil mounting bolts. Rotate the flywheel magnets directly beneath the coil poles, placing a standard heavy business card or non-magnetic 0.012" feeler gauge between the coil legs and the flywheel. The strong magnetic pull will snap the coil tight against the card. Torque both mounting bolts down to factory spec, then rotate the flywheel by hand to pull the card out. This ensures clearance that will never rub the spinning flywheel. Flywheel Rust Secret: Before installing the new coil, take fine-grit emery cloth and lightly polish the surface of the flywheel magnets. Surface rust, oil glaze, and fine debris on the magnetic poles weaken the magnetic field induction, which reduces spark voltage at cranking speeds.
