Will this test the alternator output amperage?

if i remember right it did but not positive i know longer have the item sorry could not be more help

No, the other answers are wrong. It does not test not alternator amperage. For that, you would need an ammeter. Use a DC clamp ammeter so you won't have to break the circuit. What the BA7 does check is the alternator voltage. You can also do that with any accurate voltmeter. The proper alternator voltage when the car is running is 13.5v to 14.2v across the battery.

I don't think so. It only reads errors that the on-board computer returns. It wouldn't tell you if a coil was shorting, or any other mechanical problems causing a misfire like a bad spark plug or a dirty fuel injector.

No, it is not designed to handle that kind of amperage. It is used for finding shorted circuits, and for powering up circuits to operate low amperage solenoids and relays and switches.On second thought, you could induce 12 volts to the ignition switch circuit to power up the solenoid, just don't use the Power Probe to bypass the solenoid.

Take a digital Volt meter and it will tell you if it is positive of negative.Don

Yes. It appears it provides a voltage reading with the engine running and with accessories off and on. There's a scale to indicate good or bad.

yes it will, besides you can even read the impedance value!. It also detect a loose connection between hot and neutral.

Check terminals and check voltage across terminals and also check how many amps it is drawing.

I would just to be sure. I bought one for my son to ensure that the amp and sub would not kill the alternator and battery. To this far he has nothad any issues . More of a insurance purchase.

Yes, you could check if the alternator is not charging, or if it is overcharging. Above 15 volts it's consider overcharging.

If this is a new install, then I'd check that the input voltage setting matches the power being supplied to the motor.

The device only responds to the current voltage and gives a number. If you are driving, the vehicle voltage will vary depending on the load put on your battery, the battery condition and the alternator output.

What would u like to know. I have purchased this unit to conduct leakage test of dc current in the auto motive field

I have used to to check trailer wiring with a separate battery and it works fine with that. The tip can also act as a current source or sink so all your testing will be backwards. You could not just switch terminals for positive and negative that would mess with the electronics of the unit. I would email the customer support people at power probe for their opinion. All the operations would be "backwards" for you as would all voltage readings.

Measure it with a voltmeter. Or use a battery tester. You can get a multimeter (measures volts, amps and ohms) for as little as $15. Then have someone show you how to use it. Its not hard and it's fun. Many other uses such as checking continuity, troubleshooting your car, checking electrical sockets, etc.

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

Yes, that will work. The meter reading will indicate the value of the power source voltage. Instant battery voltmeter if that's what you want.

You could test it if you had a 12 volt source and wired everything up. The unit basically just needs power and a ground.
