High pitch noise 2008 Dutchman

[NormanMatthews]

Heard a high pitch from my 2008 Dutchman trailer while packed in the drive way. I could not find anything on. And could not find the source of the sound. I turned on a light the sound turned off. Could it be a low battery indicators?

Has the emergency brake pin been pulled out and the trailer's brakes are engaged? I can hear a whine from my trailer when its brakes are engaged.

I will have to test them.

Extremely loud high pitched noise can be a propane or CO alarm.

More subtle high pitched noise can come from electronic equipment.

An inverter or converter/charger may emit a high pitched noise and it may change when current draw changes.

Anything is possible, but it is not usually due to a battery status indicator, especially one that stops when current draw increase.

Ditto, same on my 2016 Dutchman Kodiak
