5. We also have a "do it yourself" repair kit linked below.
6. I followed a blog post on how to repair my own board and after the repair when I plugged it in and turned on the ignition, it smoked and burned the board. Can you still repair it?  This is surprisingly common. We can probably still repair your board, but less likely than if this didn't occur. The more damage the board has, the less likely it is repairable.
   
7. Do you need the whole gauge cluster for the repair? No. We have everything needed to properly diagnose, repair, and test the circuit board.
