Voltage Stabilizer

[Discoburg]

I seriously dun think the VS will have any effect on the battery water level lor.

[Killingtimes]

could it be the weather is getting warmmer.....or your engine is getting hotter

[Mantaone]

If VS is not the problem

Then i think i hve to spent $$$ get a new battery

[Mantaone]

I did put a bonnet insulator thou

[Genie47]

That is why I say, all these stabilizers are good for electricals. The moment they start dragging in engine performance into the picture, things get very .......... snakey.

Irene, are u driving Corona....??

old cars w/o ECU dunnit Voltage Stab thingy.

that's why no effect.

I've witness an HVS drained a batt repeated for 1-2days.

After 3 sets of batt, the person removed the HVS, and everything is back in order.

 

What was found by doing a simple resistance measurement is very low resistance.. since its attached to + and -, it drained the batt.

 

So the HVS is "shorted"...

Can you explain difference between impedence stabilizer vs voltage stabilizer and how impedence can be stablized?

 

Voltage can be stablized through capacitor. Impedence can be stablized through capacitor.

 

 

From their website, you can only tell that z-stab works by "lowering" load on your alternator.

 

Load on alternator is controlled by a regulator, which alters load based on voltage level of the system. If the voltage runs low, alternator increases load, and vice versa. So, if you buy a good strong battery, you'll improve engine output and FC.

 

But given the same power source, there's no way to improve anything, except maybe through capacitance to smooth power spikes.

try unplugging your battery for few mins and plug in again...

 

You'll instantly experience magical increase in responsiveness for free, guaranteed. That'll last for hours -> weeks depending on your ECU learning.

 

Usually, sudden improve in response = waste fuel. It is because your car is running too rich, especially during acceleration enrichment. After you drive for a while, and your car return to the usual sluggishness, then you know you are at optimum tuning.

if u r refering to shunt regulator, definitely not recommended as it drain battery.

Capacitors store charges, so dun drain batteries, unless it is short-circuited. Should hv a protection fuse that blows when this happened.

But it does no effect on my rio as well.

[Normal_aspirated]

at least make the engine compartment quieter, and throttle response faster.

Dun expect any power boost.

Idea behind a Voltage stabilizer is actually very simple. Your car works on a 12.0 v battery and batteries use Direct Current (DC). Most if not all of your car's equipment are built to run on 12v power.

However problem with DC is that it tend to fluctuate and is not always constantly 12.0 v ie. can range from 11.1 -12.9v.

 

Some electronics may not be able to power at it's full effectiveness when power supply is crazy and inconsistent. However some car may have inbuilt measures to tolerate this voltage inconsistency, which explains why VS works for some cars but not others. Another factor would be individual sensitivity.

 

A Voltage Stabilizer (VS) has it's own batteries that help to maintain that 12v.

When it's 11.1v, the VS will supply the 0.9v from it's batteries reserve to maintain that 12v.

When it's 12.9v, the VS will charge the additional 0.9v to it's batteries for future charging usage.

 

Additionally, a VS may help to charge your car in event of drained car battery.

those VS we're talking about contain only capacitors. Basically they'r just power filtering to remove ripples caused by alternators, ignition system, DC fan motors, etc. V.S. only help to provide cleaner DC voltage for the ECU to function properly. That's why better throttle response.

the one u mentioned are more complicated ones, dun think these V.S. are made of that much complicated electronics parts. i dun think is cheap oso.

My S$0.02.

Batteries are Capacitators. Capacitator is just a fancy name for it.

I believe the power ripple you are talking about refer to static (stray) electricity. That is why we install grounding to our car to lead the stray to the chasis

yarlor, i forgot to mention to include grounding with V.S. completes the electrical filtering. Mine all done D.I.Y., & parts all from SLT. Total cost me ard S$25.00 for both V.S. and grounding cables.

Btw, do u DIY yer car oso?

I'm too lazy to do DIY. Paid Mcwell to do it for me. The guy took over 2 hours to do it up nicely. I just watch and supervise.

[Maded]

dude, how'd you DIY your VS?
