#How to test your #alternator voltage drop test

How to test alternator and how to do a voltage drop test and how to check the alternator voltage and check alternator regulator but first how to check battery voltage and battery charging voltage so how do you test battery voltage or how do i check battery voltage watch and find out very easy test on test battery with a multimeter and test alternator with a multimeter

Baking soda mixed with tap water to clean off white/green corrosion build up.

I live in a cold climate & we gotta have good connections come winter time.

When measuring below 1 Volt, use the millivolt setting on your meter. Far more accurate IMO.

Thanks for the video. If I'm not getting charging is it my alternator or regulator?

It is BEST to test for voltage drops UNDER LOAD. Just as he shows here. You can still see a drop with no load. Just won't be so drastic. If you have a heavily corroded battery terminal, you will see a drop with no load.

My tacoma has 60 millivolts drop on idle on the positive side and 40 on the ground side. My car keeps killing alternators. I can't find where the trouble is. Rip. Good video btw 👍

HOT WATER is the best to clean terminals with. All others are messy and a waste of time. Why? Most sodas are acidic. You want either a neutral pH like HOT WATER or a higher pH like baking soda to neutralize the corrosion.

Can't see where you connected your negative probe for the positive voltage drop test

[tinoweeno]

where'd you get those clamps those are genius lol

My car’s battery drops from 14.2 to 12.2 after either on the road running or idle park at around 25 minute mark, and both brake & battery signs on at the same time. Just bought a new battery. Is it a bad alternator or something else? Why it drops at or around 25 minute mark? Thanks for your video.

Good alternator, questionable lifter.. lol 😆

Hey I did the Samething instead it says -0.01. It doesn’t show any numbers? What’s that mean?

Carbonated drinks will clean the posts. Apply grease afterwards on terminals...keeps them protected from sir

Fender grounds are crap. Firewall is better. Why? Fenders tend to bolt to other panels. Those bolts will be all rusty and corroded where you CAN"T see. Firewall is the most robust panel on the car. Well besides steel bumpers which new cars lack. Grounds should be to the STARTER, - battery post, rear of alternator case for high amp alternators and stereo systems and the firewall. Why? The starter is the highest amp draw on the vehicle.
