does it test alternator output?

No. It will show volts only. For alternator output voltage is only 1/2 of the equation.
755416
No, it only tests the battery, but it is the most accurate tester to detect bad cell

Yes, it will. Make sure the battery (in the tester) is fresh, and the electrodes on the tester are clean.

It won't measure resistance. It will display the voltage output of the coil to the spark plug in real time measurements. If you have the specs you'll be able to tell if the coil is bad by the voltage its producing to the plugs. Even if the vehicle turns over but wont start, it will measure the voltage sent to the plugs on cranking. Keep in mind that bad plugs can alter the displayed voltage reading, may give the impression the coil is not doing its job.

From the PowerDrive user manual "The motor is equipped with a battery gauge. This LED gauge provides an accurate display of the remaining charge in the battery". The answer to your question is yes.

Absolutely, I test mine a couple times a year. This tester works best when connected to the battery's post.

Depends on the installed app. It will if the program allows for it. I use it with the torque app for android and can only do engine electronics but reads real time. Great item for the price. Works like a charm

I don't believe so. It is powered by the PSU and simply checks the voltage of each connector to make sure that they are within specification.

As I recall, it does. However, I got it for another manual/battery unit and as a result I'm not certain. It should indicate on the specifications section.

No. I tis designed to test off the shelf batteries. I personally have used it to test rechargables. It works on some but not on others. Have no idea why.

Yes, I use mine for that on occasion. Be careful when the car is running, the alternator could pop the fuse or drain the 9V battery in the multimeter rather fast. There's not a whole lot you can learn about the battery with a multimeter, but they are quite useful for testing devices in cars/trucks. e.g. you can test your coil packs using the Ohm-Meter (resistance) functionality.

Yes. You will be able to watch the performance of your alternator as it increaseas & decreases voltage. I have left mine plugged in all the time. Lets you monitor battery voltage with car off.Does not seem to drain battery at all.

Hi good questions. This unit will only give you readings that your engine computer has and there is a lot. Also if you have a check engine light come on you can read it and reset the computer. If you get the unit you'll be glad you did. I am.

I don't know. I used it two weeks ago to read an engine code about a fuel system problem on a Honda Prelude. It told me what I needed to know and I made the repair.

Yes. Keep in mind that it's not an advanced tester. It only tests the pins in sequence to see if each wire is connecting. If a light doesn't show, you have a bad cable. It doesn't test things like capacitance, attenuation, crosstalk, and the like.

This reads the value of the capacitor you're testing. It does not check for ESR. For detailed failure analysis, you'd probably want a more advanced tester.

It should read 12 turned off and 14 on. Any lower or higher something is wrong with your batt or alternator

Yes It will pull any and all codes that trigger the check engine light. However you should get a list of codes that are model specific. Google it.
