weird electrical issue. no tail lights or fan 84 VF700

this is a pretty weird one that I'm not making ANY sense of. my tail light, and tag light are out, the fan isnt working at all(hardwired on) but I have power to crnk the bike. seems like blown fuses right? well, the fuses are all 100% fine, gone over and no blown ones.

now, heres where things go screwy. I pull the clutch lever in, the fans come on, and the tail light does too, although weakly. anyone know why?

 

Sounds like a bad ground connection, check the negative battery cable to the frame connection.

 

yup! thanks for the hint. I totally forgot about a pair of grounds on the tail, connected those, works fine again. thank you.
