maxlftatsbcglobaldotnet. the truck has not been operating for a month or so. The previous mechanic thought it was the battery. They had the battery replaced. When I installed the battery it worked fine. I drove about 50 ft and it shut down. Now I turn the key and I get an initial contactor close then it opens. The display lights up and shows the wrench and no bars on the battery display while blinking. Twice during start up I had the contactor stay closed and received 5 bars on the battery display along with a code 67-1. This only happened twice and since then it shows no bars and a wrench while display blinks...
