Hello, wondering if you guys can help me out, I have a 89 dodge caravan turbo 5 spd base model, no power options, van runs awesome, when driving during the day everything works perfect, when you turn the lights on gas gauge goes full, volts go dead, tach dont read properly and the oil pressure gauge reads low and volts go dead, and both blinker lights come on as if the bulbs were blown. I've changed the headlight switch, ignition switch and all the fuses are good. I was wondering if any input you guys have would be appreciated. thnks
