Need help, I have an 83 venture that I had on a trickle charge for several weeks, when I then tried to start it the gauges went nuts and the starter did not crank at all. I did check the battery and it was good (13v). Now when I turn the key to on I loose all power to the dash even the clock goes off, and take the key to acc and all seems well. What did I burn up or break? Thanks for all your help on this one.
