Wires connected to the starter incorrectly or defective ignition switch.
Starter motors vary in specific location on different models and makes of vehicles. There is, however, one constant. In every case, the starter connects thru a heavy cable either directly to the battery or to a starter solonoid in the engine compartment that is, itself, connected directly to the battery. Find the biggest (usually RED) B+ cable and follow it to the Starter. If it terminates on a starter solonoid, follow the cable on the other side of the solonoid to the starter.
It could be that there is a bad connection between the starter solenoid and the starter, or that the starter motor itself has failed. Check the wires first. They're cheaper to replace. This also happens when the battery is very low, so it may be worth charging the battery if you haven't already eliminated that possibility.
If the starter is clicking, that's a good sign. Replace the battery and make sure you didn't have a drain on it. This problem could be caused by several things, but a weak battery or bad starter solenoid would be at the top of my list of things to check.
if the battery has enough power, it could be the starter itself, poss a bad spot on the motor, could be a bad connection at the starter or positive battery cable, maybe corrosion on the terminals.
the starter is on the passenger side of the engine compartment under the vehicle is the way to access it . First remove neg battery cable . then go to the starter itself and remove the pos bat cable and starter solenoid wire inspect the back of starter to see if a support bracket is installed remove the bracket as necessary. next remove the two 9/16 head bolts and dropthe starter . also there may be a stiffiner stut in the way that may have to be removed as well
It is connected to the starter. The larger part is the starter itself and connected to that is a smaller cylinder shaped part which is the solenoid itself
Battery may have been weak the previous day and when trying to start created excessive heat through the starter solenoid causing it to "weld" in the closed postion. When charged battery was installed solenoid was already in closed position. May release itself or solenoid may have to be replaced
poor battery connection or battery itself high resistance in battery cables would be some things to check plus beanch test starter itself
The starter relay is located on the battery side of the Mercedes 450SEL. It is close to the battery itself.
The positive battery cable is attached to the solenoid and the solenoid is attached to the starter itself.

The starter itself.. that would be unlikely... but a wire connected to the starter could on some vehicles.
The solenoid is on the starter itself. Usually only two bolts and the wire connections need t be removed. First disconnect your battery. Then remove the wires from the solenoid. ( you might want to draw a pic of how they were connected) Then just reverse! pretty easy! Don't forget to re-connect your battery.
If it won't turn over then suspect the starter. Check for power at the starter itself.
It should be on the starter itself or if remote between battery (positive) & starter. Just follow the cable.
A battery jump starter works by taking the charge from another battery, such as in another car, and passing it to the dead battery. When the charge is sufficient in starting the dead battery, it should then start charging itself as the engine runs.
There shouldn't be. The negative battery cable should ground to the block or the frams. There are three connections on the starter if the solenoid is on the starter as it is on a Sable. The biggest connection is for the positive battery cable. The one directly underneath it is where the braided cable coming out of the starter is connected, and the spade connector is where the ignition switch wire slides on. The starter itself usually grounds by being mounted in place through the starter bolts. but some ground internally through the brushes. .
