Installing Digital Voltmeter
I want to install one of these in my car: Mini 99.9VDC Blue Digital Panel Meter Voltmeter Voltage - (eBay.ca item 200231132572 end time 19-Jun-08 00:35:51 EDT)
Given wiring diagram:
So, can I just use a 5V voltage regulator to give it the 5V, like this: 5V Regulator at Source/RS
(Of course the meter will fail if the car's voltage drops below 5V, but then I'd be screwed anyways!)
Thanks guys.

i had 4 of this one
PHOENIX GOLD RMD-BLK REMOTE VOLTAGE MONITORING DISPLAY - (eBay.ca item 200230378450 end time 15-Jun-08 20:58:18 EDT)
things like amps, battery ,fuse and is how i knew my alt was going nfg on me

And that one only requires the voltage source which it's measuring? I guess it has a regulator built in...
To clarify my question; will that 5V regulator work to provide the power to the meter, while it measure's the car's running voltage?
Also, I really like this one since it will be easy to flush mount cleanly into a dash panel I intend to mount on.

Looking at that regulator it out puts 1A. It also states it may need a heat sink. (it most likely will in your situation.)
With that in mind I say it -should- power that display. However that auction does not list how much current that display uses, so I cant be sure.
