RV horn alarm due to generator use
While parked short term, I turned on the generator in order to use the A/C. After less than 5 minutes, the RV horn started honking, and flashers flashing. Turning off the generator stopped the honking and flashing, except for two reps of 3 honks which followed the turning off of the generator, and about 30 seconds of no honking.
Here are the details that might be relavent, that I can think of:
2015 Forester 3051S
Fridge set to auto (propane/electric, so would have switched to electric when generator came on)
A/C and bedroom TV (DC powered) were the only other appliances running.
Park break on
Full tank of gas
Leveling jacks up
Thanks in advance for any help with this issue.
