Temp and fuel gauges no bueno

@MoparMike1974 stock style aftermarket. Depending on the brand, it could be reading correctly. I’ll stick it back on the car and see how it behaves. Like I said, I was using an 18 ohm resistor. It shouldn’t have read full.

pulled the temp gauge apart. I see the broken filament. Is there any way to repair it? What is it made of?
