Rectangular black plastic ignition switch box with multiple terminals and toggle switches

BFKK

BFKK Ignition Switch Box 420cc 13HP 60340 60349 69736

SKU CH-4FXJ-0MA4X

Controls ignition, shutdown and voltage monitoring for 420cc 11–15 hp engines including Predator 60340 60349 69736 and Honda GX340 GX390

  • Compatible with Honda GX340 GX390 and Harbor Predator 13HP 420cc engines
  • Multi-functional control includes shutdown switch and voltage monitoring
  • Reliable materials ensure efficient electrical conductivity and smooth ignition
  • Dependable startup delivers consistent activation in chilly temperatures
  • Engineered for regular use providing long-lasting performance and functionality

Compatibility Range

This ignition switch box fits Honda GX340 and GX390 engines rated at 11, 13 and 15 horsepower. It also matches Harbor Freight Predator 13HP 420cc models 60340, 60349 and 69736 plus Lifan LF188F-BDQ, LF188FDP and LF190F electric-start motors. The unit replaces the original control box on compatible 420cc air compressors and general-purpose power equipment. Builders using unlisted engine brands or displacements cannot use this part.

Multi-functional Control

The box combines an ignition switch, a shutdown switch and voltage monitoring in one housing. Materials are chosen for electrical conductivity to give reliable signal transmission and accurate voltage readings. Normal operation delivers smooth ignition control without extra noise or heat concerns. The assembly is designed for regular daily use on compatible equipment.

Dependable Startup Under Load

The kit is engineered for consistent, trouble-free ignition whether the engine is cold or already warm. Sustained cranking cycles do not degrade the switch contacts or voltage-monitoring circuit. Long-term reliability comes from the selected conductive materials rather than active cooling. Equipment requiring a different voltage range or starter current profile will not start correctly with this box.

Questions about this item

How is the BFKK ignition switch box installed on a Predator 420cc engine, and what step is often missed?

Mount the box to the engine frame, connect the wiring harness to the starter solenoid and battery, then attach the shutdown switch and voltage monitor leads; the step often missed is securing the voltage-monitoring wire to the correct terminal on the 60340 harness.

What maintenance or replacement will the BFKK switch box need after extended use on a 13HP 420cc motor?

The shutdown switch contacts and voltage-monitor circuit should be inspected each season; replace the complete box if the starter relay fails to engage or the voltage reading drifts on the 60349 system.

What limit appears first when the BFKK ignition box runs continuously on a 420cc air compressor?

Heat buildup in the starter relay coil is the first limit; sustained cranking cycles on the 69736 engine can overheat the coil before the voltage monitor or shutdown switch reaches its threshold.
