MOTOR OPERTAES WITHOUT KEY

There maybe a problem with starter motor? Some of the national brand auto stores will test starter for you. Of course, you have to take it off and take it to them.


You could take the starter off, lay it on the ground, Hook up jumper cables properly from starter to battery. The starter should kick-out the drive gear and spin. If starter drive gear kicks out and in, something is wrong. Anymore I replace starter solenoid and starter motor as an assembly.

It wouldn't hurt anything to check flywheel teeth while your at it.

Just changed mine for the same problem!!! replaced starter, problem solved! Unusual design by american standard, for the main motor to continue to drive, !?

Check starter solinoid

If you are talking about engine cranking, then you should check for free operation of the starter motor solenoid. This is situated on the top/side of the motor and it\'s job is to engage the starter motor only when the ignition key is turned to the crank position. It is plausible that the solenoid has become corroded, or fused in the closed circuit position.
To check to see if this is the case, remove and clean the starter motor solenoid, and test it\'s operation while off the car.


If you are talking about continuous running, not cranking, then you will best use an endoscope and insert it into the engine\'s cylinders to view the innards. You are looking for a build up of carbon on either the valves, valve stems (when in the open position), pistons, and cylinder head. Also check the condition of the spark plugs for a build up of carbon.
Carbon is a byproduct of combustion, and can build up on some internal engine surfaces. This can cause a number of issues when running. The carbon becomes red hot and can retain it\'s temperature for a long period of time. When you turn off the engine in a carburetor vehicle, then air and fuel can still be drawn into the engine while its momentum winds down. However as the red hot carbon in the cylinders is hot enough to ignite the fuel and air mixture, the engine still runs, still turns and continues to suck in more air and fuel mixture, and continues to operate.
It may operate quite roughly and eventually stall out, as the fuel/air mixture isn\'t as efficiently burned when ignited by hot spots, and the hot spots may eventually cool enough to fail as an ignition source.


These two above examples are perhaps a couple of the most common reasons for an engine continuing to run after the ignition key has been turned to the off position, or has even been removed from the lock/barrel.
The only final reason for the engine managing to keep running after the key has been removed, is a faulty ignition lock/barrel mechanism.

Hi without seeing (hearing) it sounds like the clutch in the bendix is faulty, as the solenoid will engage the bendix at the same time as connecting feed to the starter motor.
New starter required or a good strip down and rebuild on the solenoid and bendix.
What condition is the ring gear in by the way (Starter Motor removed). David

Without hearing the sound it makes - it's kind of hard to diagnose.

The engine starting process consists of turning the key to start, the starter motor's rotor moving forward to engage the engine's flywheel, and then the starter motor 's "rotor" spinning until you move the key from "start" to "run". You can hear the starter motor spinning - but one usually can't hear the rotor moving forward to engage the flywheel. As a result, you hear the odd spinning sound - which is the starter rotor spinning. The engine never actually turns over because the rotor never engages the fly wheel. If this is the case, then it is very likely that your starter needs to be checked and / or replaced.

Good luck!

hello there
Most likely you need to replace your electrical portion of the ignition switch.It is a common problem.

it sounds like the starter solenoid contacts are not separating to stop the starter from turning.the run on is due to the starter not stopping causing the motor to continue to spin.replace the starter unit as it will have damage due to being engaged with the motor running,also have the flywheel inspected to make sure the teeth are not damaged on it.

replace ignicion

definately ignition switch gone bad, replace them. go from there.
