How to build your own Solid-State Instrument Voltage Regulator (IVR) for yourself (or build them...
So it does not seem like anyone gives much of a rip about this thread or my comments, which is fine because I often post things no one cares about during my early morning gauge rehab sessions, lol. But seriously, this one is pretty important, especially for those who have not modified their fuel gauges yet to disable the factory IVR.
After recovering from last morning's (third shift really) ^gauge mod disaster^, I have a better plan for the one pictured below, which is the final working fuel gauge I have left on the shelf. I plan to NOT open and modify the gauge, but instead isolate it's 12v post from the circular connector feed (using a nylon washer) and just feed 5v to the three gauges from my IVR via the 5v post on the FG and PCB traces on the circuit board. Much simpler and less risk of damaging these precious 50+ year-old gauges. Once again, if anyone has questions or concerns about anything I post, please let me know in the comments or PM me.
And if you need a color PDF copy of the instructions that come with my IVRs and cover the above-mentioned fuel gauge mod (especially if you are building your own), just PM me your email address.
Happy Thursday! We are almost there...
