Tell me one good reason why all cars aren't mandated to have daytime running lights?

[PNWbrit]

Uglymonkey and Blurred are rapidly becoming our very own bad tempered and irritable Car Talk guys.

From what I understand while the engine is running all the accessories are running on the alternator. The battery actually acts like another accessory while the engine is running. It draws power as needed till its fully charged, at which time it no longer draws energy.

Its true that they are all connected like that, but the presence of the battery smooths out the load on the altnerator a LOT. Its not a simple 'on/off' thing with charging the battery or not.

It is just like connecting a capacitor in paralell with a power supply to smooth out noise like from flourescent lights.

[mcsquared]

So you're agreeing with me, eh?

No, what i am saying is that on the HUNDREDS of cars that you have driven, the difference isn't something you would notice, unless you were looking for it. But that doesn't mean it isn't there. At this point I realize that there is no way you will just concede and admit you were wrong like a rational person. You are blurredelevens after all, why break character? But I am curious as to how far you will take the argument in order to obscure that fact.

I used to be a certified car stereo installer, so I think I have a little more REAL WORLD knowledge than your pedantic googlin' self.

Hmm, considering a new sig...

As for Blurred not feeling any noticable rpm change, I guess perception is 2/3 of reality. Last night we had to run up north a ways to see old folk and I had plenty of time to fiddle with this. With my Suby in nuetral (its a stick) and all accessories off the idle changes slightly when I flip the lights one. If I flip the lights on along with both of my seat heaters it is quite noticeable and visible on the tack.

I guess the ultimate test is when you charge another car. When you have a (dead)battery with low voltage and jumper to a car battery humming along at 14.5 volts fully charged the car that is running will have a very noticable change in its idle speed and load as the alternator starts pumping out its maximum amperage. This shouldn't be susceptible to the perception/reality baloney that Blurred is playing with.

So what year is your "subie"? Sounds like it has some issues.

We're talkng about DRLs here, not jumping another car. I still haven't debated the draw of the alternator, you just make DRLs out to be ths hudge energy waster that sucks energy off your engine, but more importantly is responsible for GLOBAL WARMING!!!!!

No disagreement. Turn the lights on, instant voltage drop is going to be smoothed over by an instantaneous draw from the battery.

[Blurred]

the difference isn't something you would notice,

Turn you headlights on and off and you can hear your motor speed increase and decrease as the drag comes and goes.

Reading comprehension isn't your strongest department, eh?

[Powow]

Listen here you little Google nerd. I said there is a draw, but it's negligible, about like having your side mirrors out while driving.

Have you ever installed an alternator? Seen one? Have any experience other than shit you googled about them?

I used to be a certified car stereo installer, so I think I have a little more REAL WORLD knowledge than your pedantic googlin' self.

I've installed numerous alternators, and I understand the functions of a cars electrical system pretty damn well.

Why don't you hold your breath for a while, and do your part in reducing CO2.

You missed the point. Just because you don't notice the extra load on your alternator, doesn't mean it is negligable because the effect will be hidden by your battery.

I haven't used google once. This is all personal experience!!!! from designing the electrical system for an electric car. Oh yeah, and the fact that I'm an electrical engineer

There are old morons like you in every physics class that love to argue with the teacher because personal experience!!!!! tells them that they are wrong.

[uglymoney]

Its an 02. What year is your truck?

Is this thread drift?

[mcsquared]

Reading comprehension isn't your strongest department, eh?

Quoting isn't yours, eh?

the difference isn't something you would notice, unless you were looking for it. But that doesn't mean it isn't there.

And quit trying to claim that you acknowledged that the lights do put a load on the engine and you have just been trying to argue that the load in minuscule. Because uglymoney never claimed the load was substantial. Only that it was present and the links that were provided claimed about 1-1.5%.

Weren't you like a scientist last week?

OK, douchebag.

I own a 2006 dodge cummins with the turbo diesel. Let's hear you calculate my mileage with using DRLs, and without.

Hearing the load it's putting on the engine would be substantial.
Love how you take the upper end of his "link" as well. Why not include the other percentage?

[Blurred]

What engine? 1.8?

[uglymoney]

What engine? 1.8?

Lol. I guess this is as close to a concession speech as we will ever get with Blurred.

Don't think about it as personal gas milage. Instead think of the fact that most cars probably have ~100 watt headlights. 100 W * 100 million cars is 10 GW. A large city uses maybe 5 GW. Still think its insignificant, even ignoring all the inefficiencies of the alternator, battery, etc.?

[Blurred]

Lol. I guess this is as close to a concession speech as we will ever get with Blurred.

Trying to figure out why your car is getting bogged down by the alternator.

If I was wrong, I'd say so. You acting like the alternator puts a draw like, lets say the ac compressor was good humor.

If your car is acting like that when you put the headlights on, something is fucked up, or your car is severly underpowered, and that's why I want to know.
So what engine do you have? How many miles on it?

[cantunamunch]

Lol. I guess this is as close to a concession speech as we will ever get with Blurred.

Your belt tension may have oversqueezed your pulleys.

He's want to point that out.

I'm sure.

Now you're Dodging the question. Do the math, stud.

Are you going to blame 50 cent for GLOBAL WARMING!!!!!!! because he has a hit record, and millions are playing their car stereo loud?

How about the millions of people driving with their windows down?

That's right there with your argument. Retarded, right? Yeah, I know.

[David Withеrspоon]

GLOBAL WARMING is a fraud anyways so why is this being argued? Anyone who isn't driving at least a Ford F350 to and from the supermarket is putting safety at risk. People who say they drive small cars or don't like DRLs because of the environment are lying since they're just trying to save money. Good on you Blurred for standing up to these morons!

Nice edit to spell "morons" correctly.

If you're going to continue as the Earths spokesman, you may want to edit your post again and spell "enviroment" correctly.

Get a new battery.
Or new alternator.
One of the two.

[SuperChief]

So now it's a global warming debate, STF up ride your bike to work if you're that worried about it.

I may be wrong, it happens on occasion but there will be no apologies Uglymoney you were called out because you eluded that you shouldn't use DRL's because of all the fuel you are burning because of them.

there were a few numbers posted as to how much, but what was the source? .5 to 1 % drop in economy. Maybe thats accurate but I find it hard to believe that DRLS cause that much of a draw on the electrical system. Now turn on the stereo with 300w amp, your seat heaters, fog lights and might as well turn on your high beams and I'll believe theres a .5% reduction in fuel economy.

Might as well remind you of your original misinformed post.

I don't think its ever been proven that they actually save lives + they waste gas with the extra drag they exert on the alternator. A little wasted gas per vehicle because of a mandate that is not based in science times millions of cars is a shit ton of extra carbon put into the atmosphere per day.

I like the current voluntary DRL system. I haven't pulled the fuse on mine yet, but with $100 a barrel oil coming, its becoming more likely that I will.

Proven? it's common sense if you can be seen you are more visible thus it is safer. Err, it probably has been proven, why don't you google it?

Go ahead pull that fuse, I hope it's connected to your seat heater then you'll really get some satisfaction of not burning a drop of fuel per ten tanks of gas. I doubt if it will be worth all the screeching your wife is gonna do.

Well thank you kind sir! I have indeed fixed my typo. You may not have noticed but I recently announced that I am no longer the "Earth's spokesman". In fact I just bought an H2 hummer to prove it, and yes, it has DRLs installed. Life has been so much better for me since I joined your side of the debate, and said "Fuck You" to mother nature!

[uglymoney]

Exactly. You don't have to apologize. You've said it all.

Whoosh.
