My Temp Gauge and Fuel Gauge aren't working...

Anyone ever tried building your own 5 volt limiter? Here's the link to a site that explains it:

My gauges quit working, then the lights quit lighting, and finally the blinker indicators wouldn't even light up. A new voltage regulator (limiter) was going to run me about $40! I found this site, spent less than 10 bucks at Radio Shack, and got to soldering.
The whole job took about 30 minutes. I mounted the new components in stock locations, even clipping the prongs off of the old limiter and soldering the wires to them - that way they plug into the board instead of being soldered to it!
Re-installed the instrument cluster, and VIOLA! Everything works again. While I was in I cleaned up the copper runs in the circuit board with some fine sand-paper, tightened all of the instrument clips, oiled the speedo union, and replaced all the light bulbs.
By far the best mod I've ever done. Cheap, easy, and immediate results.
