My turn signals stopped working both ways. I checked all bulbs and they were all good. They even light up when I turn the headlights on. They just don't flash. So I thought maybe it's just the fuses. I checked the fuses and they were good. Then I thought, maybe it's the combination switch, but I already changed it recently when only one side didn't flash. That fixed that problem before. But I thought I'd try and hit the hazard flashers to test this. So I hit the flasher switch... Nothing... So now I'm thinking it's gotta be a bad flasher. When it comes to the electrical stuff, I don't know where to start. What should I be looking at first? Is it the relay? How would I test if a relay is bad or not?

I saw professorzeta on zcar.com has them on his 280Z. Rota Aleica Pic

I currently have 15x7 rims on my '76 280Z equiped with 215/60 R15. I bought new 15x8 and 15x9 rims, but haven't gotten tires yet. I was wondering if anyone knows what sizes would fit these new rims. I know the widths are different, but would the tires I have right now on my 15x7s fit the 15x8s and 15x9s?
