Hi guys. I recently bought an old 1979 honda cx500. The owner told me it had been garaged for a year, so I knew there would be problems. I took it to get an oil change and check up, and one of the things they told me they checked was the electrical system.

But yesterday I took the bike to the grocery store. Put my backpack on and was ready to go, but the lights wouldnt come on. For a second I thought maybe someone had messed with my bike, so I checked if everything was connected (looked like nothing had been touched). So I sat there fiddling with the key for about 10 minutes, thinking about my options, when the lights came on full blast and everything worked fine. Started no problem and was on my way. So... any ideas what's wrong? Thanks,
