So I hooked up to the family stock trailer this morning to finish fixing the lights on it. I had the lights on in the truck and the radio on. We had just finished getting the lights on the trailer running when the radio cut off. Within 10-15 mins I had lost power to everything!!! The only light that came on was the security light and that was intermittent. I tried in hooking the trailer to eliminate it from the scenario then unhooked the batteries with the key on for a couple mins then turned off the key , hooked up the batteries again and regained some lights on the dash but no odometer. After resetting itself several times I got the security light and nothing else. Not even a ding from the door. I then tried disconnecting the ecm and the same procedure with the batteries then hooking it all up again withe the same results. I'm 400 miles from home and my wife is 37 wks pregnant. I need help guys. I'm in upstate SC now and I've gotta get back to Hampton Roads VA. HELP!
