So I picked up an Instrument Voltage Reducer at Carquest and would like to know where to mount it and how to wire the little ****er in to run all three gauges; the Fuel, Oil, and Temp, please? Here's a pic I found online, but it's exactly what I bought. http://www.jalopyjournal.com/forum/album.php?albumid=18551&pictureid=213455 Thanks!
I'm starting the same project, although I'm using one of the slightly different "modern" regulators, which I think wires up the same way. I was thinking of wiring mine to a small little terminal block and then connect all of the 6v gauges to that. Here's the diagram I'm using, I wonder if anyone has any alternative suggestions?
Here's the link to the version I'm using with some additional specs... http://cgi.ebay.com/ebaymotors/ws/e...0595310031&viewitem=&sspagename=STRK:MEWNX:IT
Looks right I would say... I was wondering if I have to run a ground wire, or if screwing the thing to the firewall would be the ground I need...and then which gauge wire to yank off, splice and wire through it...
if your firewall is well grounded then yeah just attach the black wire to it..a ground is a ground..personally i'd install it next to the fuseblock and share the ground.
I'm just curious, is your voltage regulator/reducer designed to handle all three gauges? Most I have seen are designed for one reducer per gauge. I built my own using Radio Shack parts to handle my gauges and electric clock. Works good but puts out a fair amount of heat so I added a heat sink to it. Just some more info for ya and my 1¢. Let us know how it works.
If you are using the stock wiring, find the wire that goes to the gauges, cut it and put one end to one terminal and the other end to the other terminal. No ground wire is needed if screwed to the firewall or other metal surface that is grounded. If using other than stock wiring, do the same thing. Run the power from the resisitor to the gauges by going to the firstgauge, attach it, then from that gauge run a wire to the 2nd gauge, etc.
It's in and works. Yep, it runs all three gauges, I bolted it right to the gauge housing, soldered together my own "wire harness" quick so no cutting and splicing...just used the ends that were there, and it worked out GREAT!
Did you do it pretty much the same as the diagram I posted, or did you need to make any modifications to that? I'm about to wire mine up and plan on following that diagram unless you say otherwise.
It is hooked up the way your diagram reads. I could snap a couple pics of it if you want. The wiring path is the same as the diagram, but this is how I did it so I didin't have to cut/splice any original wires... 1) pulled the ignition switch wire off all three gauges 2) bolted them together with a little nut and bolt 3) bolted a new wire from the same three I just bolted together and connected it to the "IGN" prong on the voltage regulator. (now you have 12 volts going into the regulator) 4)Now I made a wire that connects to the other tab on the regulator and splits into three wires. 5)connected the single end of that wire to the regulator and the each of the three branches of that wire to each gauge (now you have 6 volts coming out and going to all three of your gauges) I then backed out a screw from the cover on the back of the gauge cluster that houses the spedo cable, and simply slid the regulator mounting tab underneath the screw head and tightened it back up. (now it's grounded) Now if I want, I can completely unhook what I did and put it back the way it was...no cutting, no splicing...it was all done with electric connecters. (though I never will) Hope that helps!
