Can this work as a meter to measure amps on a car alternator? I need something like this to measure amps at idle, and running amps. Max 150a

You are showing a need of 150 amps of measuring range. The unit range shown is 50 amp. I think Amazon offers others that may be good for the 150 amp range that can be powered from a 12 volt battery. They will show the charge and discharge if wired in correctly. The current shunts are made to handle a wide range of current for measurement as long as you select it large enough for the application.

What you need is a current indicator. They are inductive, meaning you just lay it on the wire without actually hooking it up. For a permanent installation, your most reliable option would be the old technology analog gauges with the needle. Just make sure you buy one with the capacity to measure your maximum output. These little gauges are good for light loads and questionable accuracy, but heavy duty use is not for these wimpy little things... :)

It Doesn't work, I wanted to do the same thing. I purchased 3 of these from different sellers, but none would work measuring amps.

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.

The max amps on this one is only 200amps. The real question is how much does it take to start your car? Most cars would be more.

The maximum this meter can safely measure is 10 Amps, so it cannot measure the car battery's amp cranking capacity, which is going to be far greater than 10 amps, it would be in the hundreds. This is my understanding.

In my car I'm running a shunt between the alternator and the negative terminal to read the amps, the power was tapped from a cigarette lighter wire. I believe running the tiny power wires to the shunt would fry them when cranking.

Sorry Calvin, I think this a great meter, however, I only use it to check the voltage on my AA and AAA batteries and rechargeable batteries from Amazon..... Works Great ! Phil Pauls Valley, Oklahoma

If u run off your car battery I would keep your eye on voltage gauge. I use it in a tractor with opti idle so I don't worry about it draining my batt.

It is designed to be used on a 15amp circuit. When metered with an amp meter the highest I've seen is just under 13.5 amps.

You can try it, worse case just send it back, but I don't think it will work. Maybe you could see if you can mount it on your meter. It's a very helpful tool.

I did not try this into Amperes yetBut I am SURE this multi meter will measure even a .001 ac or dc Volt

The current for the cranking amps, and all the rest too, will only be going through the shunt. The meter will only see the difference between the two poles of the shunt which will still be in the millivolts. That shouldn't hurt it. It will just go over max reading.

I believe this meter unit works for up to 7500 running watts. It sounds like yours is 6000 running watts with a surge of 7000 watts. Yes; this will work for you.

When we received our meter it failed to work at all.The supplier decided not to send a replacement siting shipping costs to effect the return and ship a replacement. But it was intended to be used for a voltage monitor on our sailboat. I'm sure it can be used in a car.

No. And I know of no way a DMM could. Only clamp type meters do that and as far as I know their use is limited to AC.

Only if you're sure the battery is dead!! Lol... No, the amperage from a car battery is way too high. It might be a creative way to void your warranty, that's for sure.

I don't have a current meter on this but it would not work with my car or a 1amp power supply I have. It did work when connected to the 12v accessory plug (cigarette lighter) in my truck and boat.
