I'm about 80 percent finished with my 1974 R75/6 resurrection project. I took it for a ride yesterday evening and discovered that the tail light and spedometer / tach. lights were out, but the brake light works. I changed the rear bulb - still no tail light - and no lights on my spedometer / tach. However, when I turn the key to the "park" position, I get instrument lights and a tail light. The previous owner changed the ingition key assembly (lost the keys) before I acquired the bike. Could it be that some of the wires on the ignition assembly are reversed?
Also - when I activate the turn indicators, the instrument pannel light (yellow one at the bottom) flashes only once, then stops - both the front and rear flashers continue to work fine. Occasionally the pannel light will continue to work if I turn left (?), but not very often - engine has to be at higher rpm. Wrong bulbs? Bad flasher?
Note: still looking for an inexpensive replacement headlight assembly from shell forward. I've temporarily used a Vetter fairing headlight bulb - held in place with some rubber insulation. The little headlight parking light is not hooked up - should that make a difference?
Any advice will be greatly appreciated - I've not run across these gremlins!
