all of my gauges stopped working while i was trying to connect the starter to
the alternator, i accidentally touched the engine and a spark appeared. i think
there was a short but i'm not sure a while after driving it the speedometer came back but the rest don't respond, the hazard and turn signals wont work either. i checked the fuses and couldn't find anything wrong.

i did research but none of it really helped as i have a 260z. please i need help as soon as possible

 

I did that once with a '77 Oldsmobile. None of the fuses blew but pretty much everything stopped working.

Turns out it was a fusible link that sacrificed itself. These look like short lengths of wire with connectors at each end. Typically they are enclosed in small white plastic cases although in many cars the cases disappear over the years.

I too have a 260Z but it's torn down for a complete restoration. I do know all the early Z's use fusible links in addition to the traditional fuses. Hopefully you've still got the plastic cases in which to look. If not, check the service manual or maybe someone else will pipe up and tell you where they are.

Do not replace the blown link with a length of wire. Otherwise next time you'll be replacing a whole section of wiring! You should be able to find a replacement fusible link on-line. They are color coded.

 

the fuseable links on the 260 z are on the firewall next to the battery. Black and green wire.

 

Here's a PDF file of some of the 260Z wiring. It's a high-level diagram which shows how cables are laid out and some circuitry. It may help with your search.
