Running lights and blinker issues

[BigJay]

Hi gang.

I just bought my first bike...a 2001 gz250. It runs well but has been beat up and has some issues.

The rear running lights don't work, while the fronts work fine. None of the blinkers work.

Ive checked the bulbs and the blinker fuse (is there more than one fuse that could cause this?). I've also replaced the light control box on the handlebar, including the wire harness tail.

I need some help tracking down the problem.

Anybody care to give me some advice? Thanks so much.
