Regarding the dash lights, I had a similar problem. I recommend removing the cluster and then remove the potentiometer (spelling?) and just jumpering the two posts left. Also unscrew the cluster components and check the copper strip circuitry to make sure none of it is burnt. This DIY should give you some guidance on cluster removal, the potentiometer is the white odd shaped box on the lower right of the black center speedometer. http://www.peachparts.com/Wikka/W124InstCluster
