Kate has had some good luck asking a question into the wind, so I thought I'd try it here to see what happens.
My big, black, and greasy 1977 BMW R100/7 sidecar rig won't start. Turning the headlight switch all the way on results in a high-pitched whining noise from the headlight relay located on the right side of the headlight bucket pictured above; turning the turn signals on SOMETIMES results in a lower-pitched buzzing noise from the turn-signal realay in the left side.
Clicking on the picture above will take you to this Flickr photo page, which is annotated with notes and the steps I can take to reproduce the problem. Anyone reading this that could help, do you think you could follow the link, read the steps, and leave a comment with any helpful advice?
I'm hoping to prepare a lean, mean, hierarchical list of things to do when I get out there next time. Any suggestions, O Internet? I should mention that I have a multitester and know how to use it (kind of), but my grasp of "check connection" is pretty much limited to "wiggle the wire and see if it makes crunchy noises." Any tips about how to check if a wire is doing its job?
Kieran, do you know any Buckaroo Banzai types at MIT that could help?
