Honda 2000 wouldnt start. I put this gen to the test in the desert sand dunes, overloaded it tortured it. So the stator windings , the pulse generator for the spark plug and the spark unit replaced.

Used 10mm socket and phillips screwdriver to take the whole generator apart then used a 2 ended fly wheel puller to pull that off to replace the stator. very easy repair no manual needed.

Ignition failure. Spark control module bad.

1 Tested all components in ignition system per ohm readings on YouTube video. all readable units were good.
2 Ignition control module (spark unit) was the only part that could not be tested.
3 Ordered spark unit
4 Removed four screws from control panel, disconnected one cable, removed one mounting screw and reversed the process to assemble.

Testing required removing all panels and some disassembly (about two hours) still easy and reassured I was ordering the right part.

Great part

Part fit perfectly and fixed my problem. The only thing was it took way too long to get the part shipped to me. Post office is too slow.
