New to the board and new to a V20

[grady268]

Hi Guys. I am new to this board and I just bought my first V20 1986 center console. It is a little rough but will be fixing her up in the next few months. I took it for its first run yesterday and was really impressed. It has a 1996 Yamaha 150 on it and it really moves. My question is the Yamaha has three idiot lites on the tac gauge. The one on the far right is lit and I am not sure what it means. I know the middle is the oil but not sure what the green one is. I cannot find my old Yamaha books that I had and thought someone on here could answer this simple question. This site is great and is very informative. Hope to be posting more in the future.
