So I did the unthinkable. I was tightening the battery hold down while the engine was running on my 03 xl7 when the wrench slipped and shorted against the positive battery terminal. The engine stopped and now wont crank. Everything else appears to be ok. when I turn the key to the run position, all seems good till I try to start. everything turns off when I go to start (Expected while cranking) but the starter wont crank. Hoping the comunity has a nice simple fix for me. Any ideas? Checked the underhood fuses and all in tact. Thanks in advance.
