I have 1986 Chevy School bus we use for going out and doing fun things lol... but we were out last night on a black top road and all the sudden the motor died. So I stopped and put it in park and tried to start but the starter wouldn't even click. NO power but the lights and the radio would still work. The heater fan and blinkers would not. What might be the cause of this? by the way the motor is a 350 gas with a 350 tranny
