Turn signal dash indicator reversed?!

Recommended Posts

Hey guys, 

Finally, my late '71 Z is about to be finished. Only a few wiring issues are left - and I have no idea how to solve them. 

Current situation: I did the ZX alternator upgrade with harness plug instead of the old voltage regulator (seems to work fine). I did rebuild the combination switch (no issues during rebuild, I doubt I did something wrong). 


1. Rear turn signals don't work

2. Front turn signals stay solid (Turn signal switch)

3. Dash turn signal indicators are reversed and solid (means left turn, right dash indicator turns on, left front turn light turns on)


4. Hazard switch turns on both front turn signals (flashing), no rears

Fuses are fine, so are the bulbs. Could it all be low voltage related? Or is there a major issue? 

I remember when I first installed the charged (but weak) battery, the rear lights turned on barely visible. 


Thank you!

Did you rebuild the hazard switch as well? Any chance you changed the center console harness piece?

Also, you can bridge the relays for now to figure out where the problem is. This should give you solid light, but homogenious ...

@Villeman All solved!


1. Rear lights not working: Ground points (behind licences plate light and above fuel tank) were missing

2. Turn signal indicator dash bulbs were reversed 😄

Took me a while, but it was an easy fix 🙂

I had the same problem. I found it a physical pain to get the bulb out. Not much room there.
