AES CHARGING SYSTEM

[Chief Patternmaker]

Hi all- I have a 2025 build Thor sequence on a 2023 chassis. The Auto Engine Start (AES) system prematurely starts the engine no matter what the battery SOC is? Any reason why ?

Define "prematurely".

Have you created an account at the Thor Owners Resource Website with your VIN so you can view and download all documentation applicable to your specific RV systems?

OR, page 115 of the Owners Manual available at:

I don’t have the auto start feature on my Tellaro, however FWIW, the Thor Class B Supplement manual (2022 version) describes its function and use on pages 131 - 133. Factory setting is 11.9v to start. Settings can be adjusted, but with a special cable and some effort. Perhaps the module settings are wrong or the module itself is defective. I looked it up simply because I was curious.
