unhook the battery for five minutes then hook it back up, this resets the computer. before hooking the battey cables back up touch the two together, this causes a manual reset and discharge of the elecrtical system. it si called a hard reset. wait at least five to ten minutes for the capacitors to discharge before doing so, ten minuteds is plenty enough time. if you still have a light on after that, the problem has not been fixed.
