Why does the keyswitch not turn the starter?

They keyswitch may not be sending the signal to tell the battery to send juice to the starter, the battery may not be able to send enough power to the solenoid to turn the starter, the solenoid may not be ramping up the power given to it, or the starter may not be functioning and able to turn.

How does a key turn work on a starter motor?

The key turn completes a small circuit that tells the battery to release power to the starter solenoid. The solenoid ramps up the power given to it and that power causes the starter motor to turn very quickly.

What should I do if my starter switch is not working?

If your solenoid is a four wire solenoid, check both small wire terminals as one is ground and the other is power from the ignition switch. *If your solenoid is a three wire solenoid, make sure the solenoid body is not corroded where it bolts to the chassis of the mower as this is your ground path back to the battery.

Why does my car not start when I turn the key?

A low or bad battery can be easily tested with a standard ohm meter or at any auto repair shop or parts store (they usually do this free of charge). A loose battery cable connection is often the simplest of causes for a non-start. A bad starter solenoid means replacement is needed. Similarly, a bad starter is likely going to require replacement.

How to test a no power ignition switch?

A $10 test light from an auto parts store is what you need. Hook it to the negative post on the battery and turn on the key- your small wire to the solenoid should have power- touch the tip of the test light to the terminal and it should light up.

What kind of noise does a bad starter make?

For example, when the starter solenoid is bad, it usually gives off a “clicking” sound as the power enters it from the battery and gets sent straight to ground instead of turning the starter. As another example, a bad starter would probably either make a grinding noise, a “spinning” noise, or the solenoid clicking noise.

What happens if you have a bad starter solenoid?

A bad starter solenoid means replacement is needed. Similarly, a bad starter is likely going to require replacement. Most likely replacing one means replacing the other anyway. Finally, a bad ignition relay from the keyswitch can be circuit tested and repaired/replaced.

Where does the black lead go on a car starter?

The black (negative or ground) will usually lead to a ground on the vehicle’s metal frame. The red (positive) will have a thick lead that goes directly to the starter solenoid, sometimes via an electronic control box.

What should I do if my jump starter is not charging?

Why does my car not start when I push the start button?
