That baby should work great. Hook 'er up and let us know what you see.olde Heathkit o-scope!
I have some other dead gauges I'd be more than willing to ship to you for free but nothing in a fuel gauge right now (at least this week) lol!Four months later, I have an update. Based on some bench top troubleshooting, it seems like stiction may be a main issue. The gauge would indicate the proper level if it was helped with a flick of a finger. Over time, the damping fluid in the gauge movement thickens and the microcontroller is unable to provide the current to fully move the air core motor to achieve an accurate reading. In our testing, the microcontroller began to draw a large current and failed. We're working on some promising external drivers to operate the gauge. Does anyone have a non-working fuel level gauge that I can obtain? Thank you very much in advance.
