The positive battery cable connects directly to the starter. Depending on what type of vehicle it is, the solenoid is either on the starter or on the inner fender. Power for the solenoid comes from the ignition switch. You can run a wire to the solenoid to cause the starter to engage.
3 reasons either the starter is not getting power from the solenoid, solenoid is not getting power from the battery or starter is burned up.
Dirty or loose connections or a bad starter.
A starter will not disengage if the ignition switch is stuck or if the solenoid has jammed. This will cause the starter to constantly receive power.
Check to see if power is getting to the starter. If it is not check the solenoid contacts in it may be burned and not letting the power threw . If power is making it to the starter it maybe your brushes are in need of replacement or (dirt in starter ,broken magnets ,bearings or burnt wires).
1. bad starter selenoid 2. blown fuse in the circuit 3. bad ground at the starter (not likely, but possible) Start at the starter, with a test light, and work your way back through the curcuit until you find power. That's where the problem will be. If the starter has no power move to the selenoid. If the selenoid had no power in the switch circuit move to the fuse. If the selenoid has no power on the battery side move to the fusable link. Keep working your way to the ignition switch.

the starter relay.
Remove starter and bench test See if you are getting power to starter
Yes, but only when you have the starter engaged
no, the starter is only for starting the engine.
disconnect power from battery, remove wires connected to starter, remove bolts from starter (usually 2), remove starter.
Blown fuse, bad starter, bad wires to the starter, no power.
Which connects starter motor and the battery temporary to get sufficient power to starter motor.
Start by checking battery voltage and then use a test light to check for power at the starter when the button is pressed. If you have power at the starter with the button pressed it could be a bad starter. If no power at the starter then check into wiring and/or relays.
why would my starter wire burn, going from starter to battery
Putting 12V power to that "S" post will ingauge the starter.
Dirty or loose connections or a bad starter.
