There is power but wont turn over - 1998 Oldsmobile Eighty Eight

So you hear the starter clicking or no noise at all.if it is clicking then you may have a bad spot in the starter,or the starter solenoid may be bad.if you use a test light there is a large wire that is feed directly from the battery all the time you should have power on it.there is a small wire next to it that only gets power when you turn the key to the start position.if you have someone try to start the car and you check for power at this wire it should light up the test light it should be as bright as the larger wire when lite.if you have power to both wires then every thing is working in the system up to this point.again while trying to start bang on the starter if it turns over then you need a starter motor.it takes more voltage to turn over an engine than it takes to operate other systems on the car.
