mdrejhon 8 #27 July 30, 2008 Quote Yeap, you're wrong ... you can't be simultaniously draining and charging a battery I think that in some modern cars, the battery is acting as a kind of capacitor to regulate the fluctuations of electricity requirements in a car. Without the battery, the alternator load is more "unregulated" than it would be with the battery in the circuit. Modern cars have car computers and more electronics, that are sensitive to unregulated electric power, and more likely (than classic cars) to malfunction with the battery disconnected from the alternator circuit. At least, as a former electronics engineer, I can attest to the fact that electronic car systems are more sensitive to unregulated electric power, and the battery kind of functions as a capacitor to smooth out fluctuating electrical loads. There may be other electronics to smooth the alternator load, so a good well-regulated alternator may be enough -- but it is possible to engineer the alternator to be so dependant on the battery to regulate the power generated. So this may depend on a car-by-car basis. Most likely, this is somewhat of an older car, and thus might continue working perfectly fine after being given a boost... (then again that's a risk, of course...) It has been a while since I researched anything about this, so I may be wrong. But either way, modern cars definitely have more electronics and built in car computers, that critically require a clean power supply... Quote Share this post Link to post Share on other sites

stitch 0 #29 July 30, 2008 Do you live close to any mexicans? They would probably steal...err, I mean sell you a good battery for 10 bucks. Or if you have a fat blonde sister that puts out, you could probably get one for free. t "No cookies for you"- GFD "I don't think I like the sound of that" ~ MB65 Don't be a "Racer Hater" Quote Share this post Link to post Share on other sites

Here the county will tow away junk vehicles for you at no cost and a scrap yard will give you $35 for the car for scrap metal, but a thousand. Does Cailfornia just have extra money to throw away? Our tax rate is 9.3% (plus surcarges for state disability insurance and wealthy people) AND we're not afraid of deficit spending. Quote Share this post Link to post Share on other sites
