I recently have a charge battery light that is on all the time. my volt gauge i have in it is reading nearly 15v...which is not good........i have a HKS turbo timer, glowshift boost vac, water temp, and volt gauge set up, and i have the Evo-r headlight conversion done....the charge battery light came on the day i put the evo-r lights in.....i have no idea how to fix it.....
