Bringing an old thread back, but now that I have the car slowly coming back together, the LED's aren't coming on in the gauges. Is it possible that that when I re-sottered the LED's the original twist ins that they are polarized (an actual positive negative) and that if one is wrong, its causing the whole system to not power up? I had previously messed with my dimmer switch too so its also possible that it is also an issue.
Can I put a 9V Battery to the socket to get power to the LED just to test them individually?
