everytime i turn the car on it cuts off then i cut it on again and its fine then at night the lights are on and when i hit the brake all the lights dim what does that mean? Do i need a new battery or what
if the battery checks out to be fully charged and/or acceptable, try to check your connections (are they all clean and tight)? ...and what about your accessories? Do you have just a stock G or did you add or c hange stuff like lighting wattage etc.?
