If your starter easily cranks a cold engine, but “drags” or cranks very slowly when hot, there may be a “heat soak” problem. Before you condemn the starter as bad, you should perform a system diagnosis of the battery, cables and starter. Another overlooked contributor to “heat soak” is corroded battery cables.
How do you test a dragging starter?
starter dragging Check battery voltage. (12.6 V is optimum) Load test the battery. perform a starter amperage draw test. perform a voltage drop test of both the insulated and ground side of the starter circuit. be sure to also VD the battery terminals. The maximum allowable drop is 100mV per ASE standard.
What causes a starter to turn slow?
Slow cranking could be the result of several possible conditions, and as you’ve suggested, the fault might reappear or worsen. Possible causes are a degraded or defective battery, faulty electrical connection, a charging system problem, a bad starter or battery rundown when parked.
How do you stop a starter from dragging?
Heat soak can usually be solved by installing a heat shield on the starter; this will reflect the heat away from starter. In fact, many vehicles are originally equipped from the factory with a heat shield. Unfortunately, they are often discarded when the starter is replaced.
Why does my starter keep cranking?
So, if your starter keep running, the problem could be stuck starter relay contacts, a continuous ground on the starter relay control coil, or a binding ignition lock cylinder that keeps the actually ignition switch in the START position. If the problem persists, it’s not a stuck relay.
Can a bad starter cause long cranking?
Bad Starter When the starter is going bad, it oftentimes either causes a delay in starting or slow cranking though you can confirm the starter for an issue if you hear a noise coming for it. If along with slow cranking you also hear grinding noise you could possibly have a bad starter creating those extended cranks.
Will a weak battery cause a starter to drag?
Low battery usually causes the starter to turn, but not enough to start the motor.

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.
What happens WHen starter stays engaged?
The Dangers of Car Starter Staying Engaged It reduces service life of the starter resulting from the damage caused to the starter when it is pushed to rotate at high speeds by remaining engaged to the car engine after it has started.
