Buck reg introduction. Showing operation and hook up

This video is for information. I am not a manufacturer and will not produce this product. I am in hopes that the Vendors will press the Gauge MFG to fix the gauge. Or provide something similar to solve this issue.
This gauge regulator applies to buses, Gia's, Beetles std and SB, Things that use the electronic gauge.
Doing this project without knowing electronics and soldering is not recommended. Damage to your car could occur.
Finalized wiring, showing protection devices for over current/voltage. I assembled the pico fuse package... .5 amps/500ma and installed the 7.5v 5watt zener diode for voltage output protection. I used very flexible wire with high strand count and a silicon based insulation.
Caution:
The voltage adjustment potentiomenter/screw is a 30 turn potentiometer Turing the screw 20 turns CCW will drop the output voltage into safe voltage to start adjusting! Bench adjustment should be done before installing... Set the output voltage for 6.4vdc. You can use a 9vdc battery for input voltage to set the output voltage.
All buck regulators come from the factory set to high voltage output. Adjusting the voltage down to around 2-4 volts before adding the 7.5 volt 5 watt Zener diode is required, if you do not the zener and the regulator will fry. If you have already put the pico fuse on the fuse will blow protecting the Zener. The aftermarket gauges have 32-35 ohms... The set voltage of the Buck regulator seems to work best around 6.4vdc.

Here is a link to a fella implementing the buck reg... He made one mistake. He was leaving the vibrator aftermarket attached so his gauge reading while pretty good probably would have pegged or nearly pegged for a full reading... Jim kzbin.info/www/bejne/hJ6tpaGupbZoZ5Y

Gotta link to the thread with parts and schematics? I my OE gauge broke so I need to use an aftermarket for a while.

[@vwbeetlefuelgaugesystem]

There is no need for schematics. The regulator has + and - labels and in and out... So it is a soldering, adding fused protection, knowing how to put 1/4" connectors on wires properly and the knowledge and use of a DVM.... Read my comments below the video.

@@vwbeetlefuelgaugesystem which regulator did you use? I thought this was one you built. There are dozens but finding a good, easily adjusted one in a nice tight package is a bit more daunting.

[@TEDodd]

It looked like screen shots from a forum thread. I figured you had that info there.

@@TEDodd I went through a few renditions before I settled on this one. After getting it all working I used shrink tubing to cover the regulator. www.amazon.com/gp/product/B07WQJ2GD6/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
