Your 2017 ACE is probably wired differently from my 2013 ACE 30.1 which has a BCC box in the engine compartment. Inside this BCC is a circuit board and the chassis and coach battery latching relays. It also has a resettable 50 Amp circuit breaker (CB5) mounted on the cct board which can trip under some circumstances. If your 2017 has this same style BCC you might just need to reset this cct breaker. On my coach it is a bear to get into the BCC and care must be taken to ensure safe electrical practise is used (you dont want any 12v welding to occur). There is a PDF document link on the internet to this BCC with a schematic and full operational description. Search Google "FW221 BCC" for the pdf. I think it is labelled pdf "untitled" now. Maybe this circuit applies to your 2017 ACE.
