Did you ever get an answer. Mine is doin the same.
No, an electrical starter can not turn without an electrical source.
Could be a short in the wiring of the actual starter motor!! The starter motor is the first piece of electrical equipment after the battery.
To send electrical voltage to the starter when engaged.
if the light goes off it's probably the starter...
Starter relay protects the ignition switch from excessive electrical draw.
Sounds to me that the starter motor is in electrical short that is discharging the battery. I would take the starter motor to the electrical shop to be tested (or the car and ask them to check the starter).
Electrical energy to mechanical energy.
In general, remove negative cable from battery, remove electrical wires from starter, remove bolts holding starter in place, remove starter. Replace starter in reverse order.
In the car electrical system, the starter motor is the first stop after the battery, so the problem has to be with that.
Yes, if the battery is weak it will not provide enough electrical energy to properly operate the starter.
testing the starter
remove neg. battery cable disconnect both electrical wires to starter solenoid. remove 2 14mm bolts that secure starter to transmission and remove starter
