I upgraded dash lights with LED bulbs everything was fine. Then while driving all went dark no dials either.

Hi,

That is a tough one to answer simply I'm not sure what was done with the upgrade. Can you tell me what was changed, how it was done, or anything you can think of that may point me in the right direction? Also, have you confirmed that fuses are all good?

I attached a pic of the wiring schematic to the instrument panel and circled two fuses. Please check them if you already haven't. In addition to checking the fuse, make sure there is power at the fuse. Here is a link that explains how that is done:

Let me know what you find.

Joe
