voltmeter question
http://cgi.ebay.com/Red-LED-Volt-Met...%3A1|294%3A100
^^ I just purchased that I intend to install it to keep an eye on the battery when running the stereo without the car running.. so i know when to turn the car back on to keep the battery where it should be. (drive in theaters :) ) I was curious if it matters where i install it or as long as it is tied into the power i'm good. thanks!

i have one that plugs into the Cig. power, tells me in 3 stages of leds how my battery is fairing, also alternator. I havent ran the battery all the way down to test if it works, but sure works when (car off) i have bass bumping and headlights on, it blinds between full and half charge to the bass.

doesn't matter as long as there is minimal resistance in the circuit... So... connect it well to something that is connected well to the battery and you'll have no problems.
Keep in mind... digitals aren't very good and showing drops or spikes in voltage since they only take one fraction of a second worth of info and only refresh one or two times a second. If you did a 30hz sine wave at full volume that was only .25 second long, there's a good chance you wouldn't see the full extent of the voltage drop... yeah... you'll see some. but not all. You'll see more of an average. Scanguage as a voltage reader.... it generally stays in the 13.8-14.1 range when i've been cruising for more than 20minutes |
