High pitched whining noise June 28, 2017, 07:37:40 pm A bit of an odd question.When I went out to the garage earlier today there was a high pitched whine seemingly coming from my LD. I went inside the coach thinking it might be one of the alarms, but they seemed normal. The nature of this noise made it hard to determine its location. I went outside and around the motorhome. It sounded like it might be from the battery box. I have the Trojan batteries hooked up to a charger. When I disconnected the charger the noise stopped and did not restart when I reconnected the charger. Everything now seems normal.Any ideas?
