I bought this a couple of weeks ago to power the accesories and lighting I am planning on adding.

I was surfing ebay one day and found a small blue volt gauge that I wanted to add to top of this piece. I need 5 volts to power it and for some reason I cannot figure out what size resistor I need to bump it down. I could use a pot to tune it but it would make things cluttered on the inside. I want to use one of the power outputs on the PG piece to power the voltmeter on top.
I got out the dremel and cutting wheel and it fits on the cover perfect, I'll need to post some pics when it is done. My amp has a remote output that can power leds to see the power status(on/thermal) as well as the voltage status at the amp. I am thinking about adding these so that I will have one place to look at for fuse and power status for the entire system.

I got off my but and fixed my cardomain page. Page 4 has a pic of the two together. In the pic I am powering the volt gauge with a temporary 9 volt.

Watcha think?

Do ya think this gage can handle a 6 volt supply? A pair of 123 size Lithium batteris in series nets 6.0 volts. The only problem you would have, is wiring up a switch on series to the batteries, so you can turn it off while not in use.
Also, if we new the DC resistance of this device, we could come up with a series resistor that would take the 12 volt REM, down to 5.0 volts. Yes, a pot would be a good bet and once the right resistance setting was found off the pot, swap it with a resistance value, closest to that pot resistance.
Got any specs on this meter? Link?

unfortunatly it doesn't come with much, I found it on ebay also for $15. I have a couple of POTs in my old tech toolbox, I'll have to dig them out. I will need to find that toolbox either way as it has my resistor kit in it as well now that I think about it....
Ideally I want a single resistor in series with the power wire to keep it as simple as possable. The two hrns that go to the gauge come on and off easily. I am going to mount the whole thing behind the stock pass airbag cover, been waiting to use that spot since its empty anyway. I'll need to figure out an easy-on easy-off way for that cover. As it is it pulls off fairly easy but it requires a good enough tug that I couldn't do it from the drivers seat. I'm thinking magnets er something like that if anyone has ideas....

can anyone else see my cardomain page, I tried to look on a different pc and it said it was hidden?

About your cover, magnets are a good option is they do not have any EMI issues with your meter or other devices near by. Velcro might be a good option as well.
As for the resistor needed, it would be good to start with a 10K pot and a reference voltage supply. The pot needs to be in series with the meter. Dial in your pot from max resistance to min resistance and read your voltage at the meter power inputs. Once you get the 5.0 volt reading, measure the pot value and make up a resistor pack to come as close as possible to the pot value noted.
Is this meter fused as well? If so, try to match the resistor wattage value to the fuse or as close as possible.
Hope that helps,
Swez
PS Am sure you already know these steps... but may have just forgotten them with time. Besides, other that are tracking this post may want to do similar things too. Now they know the steps.
