I thought testing and explanation of the battery voltage and starter couldn't possible be more simple but this video is absolutely amazing at explaining it in terms even my 9 year old can easily understand. Thank you so very much! 😇 Now I can simply watch this video with my little boy and if for some reason he has a question I can answer it or maybe and hopefully this channel will have a simple explanatory video that will answer his question as well. Love this channel!!! 😇💙

If you want to check battery. You do not use multimeter. First you must charge battery with battery charger. If battery do not charge it is bad. When battery is charged you test it with charge tester then confirm if it is bad or good. More advanced way of testing battery is by using programmable load. You can measure what is capasity of battery.

Its always good idea to have jumper cables in your vehicle, batteries do not last more than 4 years in hot parts of the country, if your engine always starts on one click you will never know if your battery is weak and will give no warning when it fails..

If the volt doesnt go back up few seconds after starting, does it mean that the alternator has a problem?

So if my car battery is 12v when ignition off, 11v when ignition on and 14v when engine on, there is nothing wrong with it? My car is not starting up first time and came up with battery light while trying to get it started but light goes off when engine does finally start up. Tested battery, spark plugs recently changed, what could the problem be?

Now why do my grasscutter die when i remove the battery? It got an engine. Same for my ATV it doesnt run without a working battery. ATV even got a rope to start it but still it wont run without a fully working battery.

@KeithWhittingham

Good question. 1/ The battery provides a pretty well constant voltage with a large capacity to provide current so - a really good power supply. 2/ While a generator can provide electricity on it's own, an alternator can't - it needs a currently flow to produce power. You could, in theory build in large capacitors so that you could remove the battery when running but you would need to start the engine with a battery.

what does it mean when my voltage goes to 16 while my machine is running?

dont forget alternator also provide current to engine ignition system to spark fuel in stroke cycle.

A jump start basically puts the working battery of the donor car in parrallel with the dead battery off the recieving car. Thats why you connect red to red, and black to black.

It's always best to use a manual battery load tester! They're only about $20 and you will almost never use it. However, when you do need to use the battery load tester just before winter it will save you a big headache before the cold weather starts to kick in!

So think twice before installing overpowered amps/subwoofers on stock battery and alternator... and maybe even throw in huge capacitor just to have one extra device for your vehicle to charge like it's not enough already :D There's just not so much it can provide extra taken into account what the car needs for itself.

I have seen that you can test a battery admittedly an AA one with a 100ohm (5W) resistor in series with the multimeter set to current (amps) can you do this with a car battery to test how good the battery is??

@Total-Solutions

3 жыл бұрын

Using the AA battery as an example, that small battery would deliver a peak output about 4 amps for your test, 3-5 secs. The good car battery would deliver approx 700 amps or more. Do not attempt this as your connect leads will melt and your test meter could blow up in our face. The good battery will continue to deliver 100's of amps for some time. In your example of the AA battery consider to place the 100 ohms resistor across the battery terminals and safely measure the Voltage (rather than the current). Just measure the voltage with no load and then with the resistor. It's a judgment call to say if the battery is then good or not. 1.6v no load and 1.4v with load, its good. 0.95v no load and 0.6 loaded, not good. Why the difference ? Consider an additional resistor of hundreds of ohms inside the battery than start out being 0.005 ohms and over time goes up in value to 100 ohms. That internal resistance prevents the current flowing, as the battery ages.

Definitely! Just checking the voltage of a battery is not enough. You have to put a load on it to see if it can push those amps (for starting / turning over the engine) without faltering.

you say that once the car is running that the electrical needs of the vehicle are powered from the alternator but doesn't the battery continue to run all the electrical needs of the car always and the alternator is just providing more current to the battery for those needs as well as charging needs?

If the Alternator is spoiled, can an engine runs on Battery Power Alone until battery is dead?

Why can't the alternator and starter be one and the same unit? they are both electric motor / generator correct?

@2aminitials

3 жыл бұрын

Starters are gear driven and mesh to the engines flywheel or flex plate (depending on the transmission type). Using the starter as an alternator would require constant engagement of those teeth and would be noisy and wear out the gears. The alternator is belt driven and would require a substantial belt capable of transferring high torque to start the engine. A belt system heavy enough would be a bigger parasitic drag on the engine as it is running as compared to a normal serpentine belt driving the alternator. You'd also need to deal with the current flow coming from the battery on startup and then switching to current going back to the battery if you used a starter / alternator combo.

@@2aminitials great explanation thank you

Great video! Might have included the fuel injectors and how a weak system can cause start problems.

The alternator charging will turn on and off while driving - the voltage regulator does this, to prevent from overcharging the battery. You can usually see the battery level gauge on dash move back and forth a little while driving. This will tell you charging system is working...if it doesn't, you may soon have a low volt situation...engine likely to start running erratically (as fuelpump and fuel injectors begin to falter).👍 Be familiar with your battery gauge operation and always monitor it while driving - that's what it's for!

One thing that doesn't quite make sense is when both the alternator and battery are powering electrical components simultaneously, how can current travel in both directions in the negative ground battery cable connecting to the vehicle chassis??? If the alternator is charging the battery, then you have current going to the chassis from the negative battery terminal to be grounded but if the battery is also powering electrical components you have current flowing back to the battery from the negative ground cable to the negative battery terminal. How can you have current flowing in both directions at the same time??? I do not think the electrical demands of the vehicle will ever reach the point where the battery will kick in to aid the alternator in powering those components. Aren't alternator max amperage close to 100A. Can someone please explain this to me, would greatly appreciate it.

Same thing. A dying battery is simply losing its capacity due to sulphating of the electrodes.

A charged car batterie puts out at least 12.6v. With the fuel pump fuse removed: - The battery voltage drops during cold cranking to around 10v. Cold cranking voltage varies with the temperature of the battery. A good battery will go back to 12.6v quickly once you stop cranking.
