Control Board for Onan RV Genset model KY, Beginning Spec J

Reverse-engineered to be more reliable than the original!  Made in USA - Not China like the original!

2 year mfg. warranty - Not 90 days like the original!


  • Exact-fit replacement for Onan 327-1413 and 300-5046 control modules.
  • Status indications for cranking and normal running.
  • Does not shut down because of minor faults, like the original.
  • Keeps running on all faults except for loss of stator voltage.
  • Does not generate fault codes. These can be confusing and misleading.
  • Since the engine keeps running, normal troubleshooting methods can be used.
  • Over-sized heat sink for cooler operation.
  • Encapsulated in automotive grade urethane and is fully repairable.

Has 23 pin connector on the bottom & heat sink on top.

Fast shipping... the board is very well built looks and feels like oem except the heat sink is much bigger. (best of all) I installed it and it works well. I will do a follow up later to see if it is still running strong.
