So I recently bought a 2005 Fleetwood Bounder 35E I really good cosmetic shape. However being my first coach, (previous was a 1984 Silver Eagle Tour Bus )( whole different BEAST) i am very ill informed.
So to the issue

, If I plug 50A shore power the genset tries to start when I throw a general 20 amp breaker. or unplugged if I click the aux battery switch.
Is this a procedural issue? Is there a sequence to switching over? Or does it sound like the ATS isn't switching or is stuck in between.
It's all new to me, previous owner only owned it a week , so I have little to go on. I have the manual but its vague. any input would be appreciated is there a systems walk through video or manual for this model so I know what normal is?
