My dad and I are thinking about building small module that will make the alternator dummy light work again. It could also add a relay to cut off things if the voltage gets below a set amount. This means it could cut off your amp and stereo to save power to just get you home. I know we're going to build this for my car but wanted to see if there was an interest to sell these on the board. Depending on price it could cost between 50 to 75 dollars. Pretty cheap insurance if u ask me...
