I have a 2009 VTX1300T. Recently, my signal lights crapped out. The taillights and horn work, so I don’t think it’s the fuse, so I replaced the relay (seemed like a good idea at the time), but no dice. The marker lights work, but go out when I go to signal. It affects all four lights. Bad ground? Any ideas, or should I accept my limitations, and bring it to the shop?
