1984 Mercedes 500 SEL Ok. I have checked these forums and 99% of the
time it seems to be the rheostat. I removed it and made a jumper wire,
so that is completely out of the picture. All the bulbs are good, and
I replaced every single fuse under the hood with new ones, and i still
have no dash lights. Could it be the radio, the car was sold to me
with a aftermarket SONY AM/FM cassete deck, maybe the installer
messed up? Which wire would be for illumination? Please help, this is
one annoying problem.
