Must be something catching about speedo R&R - just done mine and the temp/fuel gauge is dead. Based on 0v at the temp sender (ign on) I am guessing same as above - voltage stabilizer? Based pics above, can I assume its on the back of said gauge? I have a solid state unit ready to go in.
Not as easy as I had hoped... Speedo came back from recalibration lacking the white plastic insulator, didnt notice that, and now I have more damage to the circuit traces. The one to the gauge has previously been repaired, and now the line to the right turn indicator light is also burnt.
