1 Answer


Dead cell in battery, bad ground in system, tensioner could be froze up, belt stretched out, etc. My first suggestion, put your battery on a smart charger. Does it come back with any codes, like dead cell? Next, if battery is fully charged, start car. Put one end on voltage tester on positive battery post, the other end ground to engine. Make sure tester in on dc volts. Normal output is between 14.2 to 14.4 volts. If you do not have access to battery charger or tester, some parts stores will do this for free. Call around.
