I recently woke to find my alarm acting crazy..lights blinking horn honking. I had never even used it before.I unhooked the cable from the black box under the dash to dismantle the alarm. After replacing the battery, Starts fine, but when putting in park I hear a clanking noise from under car and car dies. Car starts right back up, but if I switch into reverse ..it makes a clanking noise and dies...so? any clue whats going on anyone?
