I have problems with dimming lights and such on my car and i wanted to kno if anything like this would help?

 

I'm not sure about that stuff. I assume you have a system thats why your lights are dimming? If so, maybe ask in the Audio/Video/Seciruty forum, they may have some suggests for how to correct that.

 

the only effective way to regulate power is by putting a transistor voltage regulator in series with the input power and output load device (your car's accessories/engine circuitry is the load device)

Another way, but very cheap and not exactly reliable is to put a zener diode voltage regulator in parallel with the load.

I wouldn't be able to tell you if what they say is true without tearing that thing apart and seeing how it works, I do find it hard to believe that it regulates voltage through the cigerette lighter circuit, especially since it has to go through a 15-20A fuse, if anything it has to be the zener diode, but it wouldn't be the greatest regulator in the world.

It's a very interesting concept though.

But then again, black and decker makes a device that can give you a jump start through your cig lighter. So this little device might actually work...

 

That's assuming the Black and Decker thing works.

As mentioned earlier, the accesory outlet is fused at 15-20 amps. No way are you going to "jump start" through that. What the B&D does is slowly trickle a charge into a weak battery. Sometimes this is enough to get you going. If the battery is totally dead, forget it.

But back to the original question. Your electrical system already has a voltage stabilizer (regulator). If the lights dim it's because the system (battery/alternator) can't provide enough current. A little bit of diming at idle is normal. The only way to totally eliminate dimming is to have a stored reserve of power. A very large capacitor would do it, so would another battery. These devices would need to be charged however, and that would in itself cause dimming.

not necessarily true, the time constant for a capacitor is always 5, (don't ask me to explain please). When you get the capacitor fully charged it should act like a voltage filter, when your accessories/lights draw energy it will draw from your battery, your alternator and your capacitor, the one with the highest voltage level is going to be pulled down to match the next highest, and then to the next highest untill all 3 sources of energy are being drawn from at the same time.

The main purpose for a capacitor is of course to fix the quick voltage drops, as it will compensate instantly untill about 1 time constant has passed and then you'll be right back to drawing off of the battery/alternator again, so yes, you will still dim, but it'll take a little longer.

As he said, those battery charges are the biggest pieces of crap ever made, you can't get anything more than a trickle through those things. I've actually burned one up trying to charge a dead battery, the circuit started to let out the smoke. Went back to the store, traded the POS for the normal jumper cables and it started instantly (more continuty = faster charge).

 

Not to nit-pick here, but they will all be at the same voltage potential if they are connected together. Their ability to provide current (amps) is what's important to reduce or minimize brief dimming when the system gets heavily loaded. The cap may help for very brief load draws (thumping bass, etc) but is otherwise a poor choice for reasons you mentioned.

These posts are begining to drift off topic and I am really trying to avoid getting into debating the validity and worth of grounding kits and voltage stabilizers here, so I'll just bow out now.

 

you're correct, I was simplifying how it works in an extreme case.

To finalize, the only real way to maintain a constant voltage is to increase the input voltage and decrease the output voltage, you will never get more power out then you are putting in without some form of transformer, and in the case of a transformer you lose amperage capability.

 

the only way to get more power is to make more power.

a cap and another battery aren't going to help, there just gunna make the alternator have more to charge. I mean, yeah it will help for a split second, but its just a bandaid.

Get your alternator load tested and if its ok, grab a HO alternator

btw that thing is retarded. it would never work.


if i were going to pay $80 for something, i'd atleast want to know the website was edited by someone other than a scam artist.
