You did not design the regulator, you put some sketchy shrink wrap on an off the shelf part, as a casing, instead of an actual proper casing. Don't burn your car down. For the electronics, what voltage, and what is the maximum current?
Listen to what I said... " Implemented into". Current? You can figure it out, it sounds like you have some experience. The minimum resistance of the sender is 10 ohms, the gauge resistance is 30 ohms. The voltage is 6.4 vdc... If you watch a bit more you will see that I implemented a .5 amp pico fuse on the input to the regulator. Then I added a 7.5v 5watt zener on the output of the regulator to prevent over voltage if the regulator had an issue. Since you seem to know a bit about electronics you should be able to explain the need for that into the design to implement the buck regulator into fuel gauge system. As for the wrapping it is high temp shrink wrap. It was needed to keep from shorting the regulator on the metal parts of the car. So the current is what? 160ma max. Design? Well I did use a buck regulator then designing the needed protection and correct wiring is a design adventure eh? Maybe you have a 69- to 8x beetle etc that has an inoperable fuel gauge eh? If so I have provided you a way isolate which component is defective and resolve the issue. BTW many other makes of cars use the same basic methods of the fuel gauge system. Many do not have OEM parts to make the OEM gauge work so they end up putting Aftermarket gauges etc on the dash of their vehicles. The VW's, there are no OEM parts avail to make it work with the aftermarket gauges nor regulators... This is the direction I have offered as a solution for those that want their gauge to work properly! Many VW's folks want to keep their car as close to orig as possible.
@@vwbeetlefuelgaugesystem what is the input voltage? With 160mA, i would just use a linear regulator. As for the heat shrink, that stuff is fine for cable but will break and tear over time on pointy surfaces. I would suggest you use a proper plastic enclosure.
@@commandoPR There is no pointy surfaces and it is secure from any vibration. My goal for it was to protect it from someone poking around in the area where the regulator is secured! Maybe you have not seen the exposed wiring in a vintage vw... It is scary! I only make 4 of these and decided I wanted something different, smaller and more compact. Watch the final video and you will see that I have settled on the encased buck regulator. That is what I would recommend. I am not selling, nor making $$$ off of the tube. I only want to offer a solution for those VW guys to have a fuel gauge that works. I have been corresponding with an engineer in Sweden and we have been corresponding with the gauge and sender mfg. JP Powergroups... They are not interested in a solution, only $$$$$$. My tube channel has had over 80,000 views... Huston has a problem eh?
@@vwbeetlefuelgaugesystemi'm sorry you feel offended by my advice. If you're scared by the exposed wiring in your vehicle, i would suggest to do a proper rewiring. It should not be scary.
@@commandoPR Oh not at all offended! All VW's from 1949 had exposed wiring under the hood, front. Not scary to me but I have seen the results of folks working on them that are not careful when working around the exposed wiring. www.jbugs.com/store/graphics/00000001/25/main-wiring-harness-pic6.jpg
