First of all, sincere thanks to all who answered my questions regarding the locations of the lighting transformer and the oil pressure sending switch on my "F". Much appreciated! It appears I need to remove the main light switch to check out the wiring there. Can someone advise of how to remove the switch knob so that I can remove the switch? No Allen screw on this knob... Also -- can the interior lights be turned on with the main light switch by rotating all the way counterclockwise? I don't find the speedometer light in the Service Manual schematic. Am I overlooking something? I've been under the impression it wasn't electroluminescent, but was instead a conventional 12V bulb. Am I mistaken? Thanks for any help.
