A new starter remains engaged while the engine is running primarily due to a malfunction in the starter relay or solenoid. When the engine starts, the ignition system should cut power to the starter, but if there's a wiring issue or a stuck solenoid, the starter gear may remain in contact with the flywheel. This can lead to excessive wear and potential damage to both the starter and the engine components. Proper diagnosis and repair are necessary to prevent further issues.
If the starter is whining while the engine is running at an idle you have a problem with the ignition switch or the starter solenoid is stuck. The starter should not be engaged while the engine is running unless you are holding the key over on the start position.
The starter will not stop the engine from running once it is started. You have another problem.
With the flywheel spinning at about 1,000 RPM at idle, the starter, if engaged with the flywheel, would be forced to spin between 15,000 and 20,000 RPM. Once the engine has turned over and is running, the overrun clutch will release the starter from the flywheel and prevent the gears from re-meshing (as in an accidental turning of the ignition key) while the engine is running
Using the pull starter with the engine running can cause damage to the starter mechanism and the engine itself. The pull starter is designed for starting the engine, and engaging it while the engine is already operating can create excessive tension on the starter cord and internal components. This can lead to potential breakage or malfunction of the pull starter system. Additionally, it may pose a safety risk if the cord snaps or if the engine stalls unexpectedly.
If clicking while trying to start then might be a bad starter. If clicking while running, then might be valve/lifter noise.
Never disconnect a battery while an engine is running!
At the back end of the engine is a large ring gear connected to the engine crankshaft. If there is a starter (some engines do not have starters) it will be mounted in the engine such that the bendix gear of the starter can engage the ring gear and spin the crankshaft. It's called a bendix because it jumps out to engage the ring gear (while the starter motor is running) and retracts off of the ring gear once the engine is running (starter motor no longer running). It is typically access from under the car. If you must replace it, let the engine cool off first. Otherwise the starter will be just as hot as the engine is.
No, I would seek another answer to the problem. If the starter starts while the car is running, it may grind the bendix or the starter into a toothless nub and the starter will quit functioning alltogether.
Yes. The alternator is used to keep the battery charged, while using the headlights, radio, a/c, etc. The starter to me is misstated because it actually cranks the engine. The ignition system starts it, and keeps it running.
Bad ignition switch or starter solenoid
The remote just connects the starter selenoid with the battery, when it completes the circuit, the engine starts and will run until it runs out of gas or the engine is disabled.
If you're implying that it engages without you turning the key, the problem is one of the following: * a faulty wire somewhere, * the starter solenoid was connected wrong * or the solenoid return spring has broken.
