I have taken a video however it won’t let me post it. But it sounds like a weak horn noise coming from the passenger side plenum drain when I’m charging my battery. I’ve disconnected it, removed and I am now charging it. But does anyone know why it makes the noise when I connect it and charge? I’m guessing the battery is dead and I’ll need a new one, however I’m worried it may be something bigger than that.
