I have an 88 Bronco 2 I got it a couple weeks ago I change the starter water pump and thermostat and starter solenoid ran fine. a couple days ago I went to the gas station ran fine got out to pay for the gas came back out no lights no power no nothing would not start.so I towed it to my house and I change the ground cable. I'm getting power to the solenoid but still no lights and won't start
