Once you get your boards repaired, put in bulbs, apply 6v to the board and see if they light up. Replacing the voltage reg for the board is a good idea.
I just made my dash harness and installed LED's they look good, just make sure they are oriented(polarity specific) properly.
Thanks... I just need to find out where I can get the original style bulbs/holders, I was hoping from CI, as I have to place an order there anyways, and hoping to combine shipping, that costs a small fortune being based here!
