I was driving home and my Jeep started making a weird noise and then a warning popped up about battery voltage I was really confused so I pulled over popped the hood it looked fine but just in case I decided I would go to the nearest VIP which was probably 5 miles from where I had pulled over maybe even shorter. As Im driving over there my Jeep starts smoking so I pull into VIP and pop the hood we look at it and my alternator is smoking so we pour some water on it to cool it down. After doing that a little bit and it stopped smoking as bad we let it sit. A couple minutes later the alternator catches on fire so kept pouring water on it till it completely went out and stopped smoking.
