Can a starter motor run continuously?

A starter motor should never be operated at no load or at full load for more than a few seconds, perhaps up to a minute. They are designed to operate in a fault mode just long enough to start the engine. Even at a moderate load, they do not have sufficient cooling for continuous use.

How long can a starter motor run?

Starter motors are designed to be operated for a maximum of about 30 seconds, with a 1 to 2 minute cool-down period between operation cycles. If you try to operate them continuously under load, you will wind up with melted down rotor and stator windings.

What causes a starter to stay engaged?

If it shows you have power, this may be the reason your solenoid is stay continuously engaged. The reason for this may be a bad switch or the cables may have a short. Please note that switches have been known to work intermittingly. Lastly, low voltage can also cause this issue.
