Will Cummins Onan EC-AGS+ Work With Onan Quiet Diesel Generator
Updated 08/08/2026 | Published 07/26/2026
Question:
I have an Onan Quiet Diesel 8000 in our motorhome and would like to add automatic generator start before our next trip. Will this work with the QD 8000 or do I need a different version for the diesel generator?

Hey Mike! Yes, the Cummins Onan EC-AGS+ Auto Generator Start System # CM58GR is the version you want for your Quiet Diesel 8000. Cummins lists this system for the HDKA QD 6000 and QD 8000, along with the HDKB QD 5000/QD 5500 and HDKC QD 10000/QD 12500 diesel generators.
Once installed, you can use the app to manually start and stop the generator or have it automatically start based on battery voltage or interior temperature. You can also set quiet hours so the generator won't automatically fire up when you don't want it running.
