Your starter may be bad: If you have good connections to the starter. A good fully charged battery. No major engine trouble. Starter still turns engine over slowly. A shorted out starter will not only run a battery dead but can ruin a battery. Also since the starter is taking all the power, the engine may not start even though it is turning over. Three ways to check a starter: If your headlight goes out or dim while trying to start it, it may be bad. Take starter out, use a manual and multi meter to check it. Take starter out and have it checked at the dealer, call them first. Good Luck
