New to forum having recently purchased a 1973 Arrow 200-R. Love the aircraft, instrumentation is old but enough to make an old retired TWA captain drool. (ADF, LORAN, you get the idea, engine analyzer) Problem is with the instrument panel lights. They just don't work and everyone I talk to says "Don't even try to fix them, too much trouble". Apparently the potentiometers (rheostats) have always been a problem and location of switches turns out to be a night mare to work on--any suggestions?? Capnzee
