I was driving my 85 cutlass with a jensen indash tv home from getting some food and i hit a small pot hole. Trust me i hit worse. Anyway my radio cut off and power antenna went down. I thought it would just be a small problem but every other electrical item works. Now the tv doesn't go down and it will try to cut on and cuts back off every 10 seconds. IT feels like its trying to cut off but theres something thats preventing it from getting any power. Any tips?
