I'm changing headlights & trying to clean up the rats nest in the shell. Just so you know it's a 1973 850. And I have mounted a set of aftermarket mini turn siginals, bike is still Positive ground & runs a Boyer... 1st dumb Question. Are the Speedo & Tach lights suposed to be ON all the time the key is in the "run" position??? Or are they supossed to come on when the headlight is switched on? Thanks. One question at a time.
