ENGINE DOES NOT START | Ignition switch failure

IGNITION SWITCH FAILURE
Here are some symptoms of ignition switch:
a. Failure in starting vehicle
b. Stalling
c. Jammed key
d. Jammed steering wheel
e. Car starts but stalls
f. The accessories are not powered
g. Flickering lights
h. Quiet starter motor
If one the above-mentioned symptoms occurs you need to test run your Ignition Switch, the steps are as follows:
This can be done in two ways:
1. Testing it with a multimeter:
I. Rotate the ignition key to the switch-off state. Back-probe the power feed wire of the module by utilizing the positive leads on the multimeter.
II. As the key goes to the running state, you have to measure the voltage. If the battery voltage indicates anything below 90%, then there lies an issue within the ignition mechanics.

2. Testing it with a test light:
I. Turn off the ignition switch and disengage the module wire connection. Detach the solenoid's S terminal as well.
II. Turn the ignition key to settle it in the run station. To test the voltage, probe the red wire connection and the battery terminal in the ignition coil.
III. Set the switch to the 'start' station and probe the battery terminal in the ignition coil and the module's white wire connection to investigate the voltage.
IV. If you witness no voltage, the switch and the circuits have errors.
