Help! 710 Sedan electrical Issues

[Datsun-San]

I'm Will Kingstone, and I recently purchased a '75 710 2 door sedan off craigslist for $700 in Freemont.

 

The car is immaculate, and was a one owner "granny" car for its whole life. Everything is stock and functioning, and the car runs like a dream. The only issue I've had so far is a tricky right turn indicator light. The left clicks and works fine, the hazards also work properly, but the right does not make contact when I flip the lever.

 

I'm going to examine the problem again later tonight but was wondering if anyone had any knowledge of 710 electrical systems or had access to a colour wiring diagram?

 

I'd be really grateful if you could help! :)
