One of the easiest ways to test the integrity of your alternator is by using a very simple device called a voltmeter. Here's how to perform the test. The very first thing you need is to measure the voltage output of your car's battery.

If the battery is working properly and nothing is wrong with it, then it's the alternator that will more likely cause a problem. A simple test to check the working of the alternator is by running your car; and then unplugging the positive connection of the battery.

Firstly, it is important to test the voltage output of your vehicle's alternator to see whether you in fact need a DC – DC charger. If your vehicle is producing > 13.7-13.8 Volts then the majority of the time purchasing a DC – DC charger would in fact limit your charge rate to the second battery.

The most common reason that your alternator is not charging is because of a damaged alternator. The way to test if your alternator is damaged is by using a multimeter. You should carefully tap the alternator with a hammer when the car is running in order to test the levels and determine if the alternator is at fault.

To check a car battery, turn off the ignition and pop your vehicle's hood. Hook up a voltmeter to the car's battery by connecting the red lead to the positive terminal and the black lead to the negative terminal. If the battery is in good condition, the voltage will read between 12.4 and 12.7 volts.

No, CKP(crank position) sensor generates it's own power, and in any case CKP wouldn't be even close to causing your problem. Your issue reads like alternator has failed to provide enough power to run the system. Put voltmeter on battery, after charging it, you should see 12.2v or higher.
