I recently stripped my 2001 Suzuki Bandit 600, and in the process of putting it back together I left the front end naked and converted to a single headlight. Everything is fine other than my tail light not operating while the bike is on. Both brakes power the light, but there is no low running tail light. I'm wondering what I might have changed at the front end of the bike that could have affected the tail end. Any ideas what my problem is here?
