Clamp Meter Automotive Measurements

Measuring cranking amps, battery charging current and others

[@whatworkedforme]

great information especially with the reasons for such high initial amps with just ignition on. Practical use of the device too. Thank you.🕶

Excellent video, thanks for sharing!

Thank you very much for this very helpful Video. I ' ve got same Multimeter and used it last weekend same way you described to make the car running again. Obviously the current value depends on the direction you use the clamp surrounding the cable. Positive value was lower than negative value and positive value seems to be the correct one. I controlled with second multimetett in series. Thanks a lot.

You are welcome

Again, nice video! 👍 Note that for accurate readings, you should position the clamp next to the cable to want to measure, then zero the device, and then clamp it onto the cable, with as little movement as possible. Zeroing the device at a random location could give a small false reading when clamping it onto a cable

You are right, I should do this. On the other hand with the amperage I read it is not significant (at least for me). Thanks for the comment.

Thanks for this good video that's helping me too understand how to begin to fix my 99 subaru outback wiring harness issues 👍

Glad it helped

Hi Robert, Good video, I have parasetic drain. I know its better to measure on the negative but is it also possible to measure over the positive because my meter doesn t fit between my batterie and measuring clamp?

[@robertdeptula2003]

Keep in mind that small current may not be picked up by a clamp tester. On my channel there is video in "Cool Tool" series about small Amp tester you can plug into fuse port and check this way.

What should the amp rate be on a battery that is good, I was told that higher amp rate means the battery is accepting charge and low rate is dead battery?

Is there a way to test how much my truck draws with the headlights on, radio, and ac to see how much overhead I have to add stuff before I need to upgrade my alternator? Is that what you did at 3:45?

[@robertdeptula2003]

With all mentioned components on you will read the total current drawn (you are right, as @ 3:45).

good clear video thankyou
