calj... Had to look up where you were... Richmond. I used to live there. Plenty of places I'd want food from there too! I try to ride up at least once a year (Rt. 5). I'll you know if I do this spring or summer.
For grounding the dash bulb and the signals... I added a ring terminal and got them on the headlight bucket bolts behind the grounding nut. Is that the best place? I know on the back of frame near the battery there is a spare ground with a spade terminal. I was using that for a brake light modulator, but now I'm using it on the EP34 flasher and grounding the modulator on the frame with a ring terminal. I wasn't sure if there was anything else spare in the bucket for grounding.
