So, I've had this tribute for about 4-5 months, I noticed the day I got it that there was a rather loud whine under the Bonnet but my parents assured me it was nothing to worry about, I personally thought it was the alternator dying. Cut to tonight where I accidentally drove through a muddy puddle ( was trying to avoid sliding into some ruts) I think some water may have gotten into the intake (car initially had no go so I just let it idle until the rpm stabilised) I drove it maybe 20 meters before it bogged down again, I again stopped and let the idle stabilise and upon taking off I noticed the battery light having its own little rave, at first I thought it was just a loose terminal so I did what I could and drove back to flatter ground for a closer inspection, above 1200rpm the issue completely disappeared but would come back immediately if rpm dropped below 1200. I managed to get it back home and I rinsed the entire car with the hose in hopes that there was just dirt or something stuck in it. In the video if you turn it up loud enough you can hear a whining noise which I believe is the alt, if anyone knows what IS wrong please help me out.
