I recently bought a 67 SS Tribute. 350 Stroker & 4 speed. My signals wouldn't cancel on a right turn, so I installed a new switch. I also fixed the horn while apart. The pin and spring were missing. Now, I have no signals or 4-ways at all. Nothing at all happens when I try to use them. I hooked up my old switch (not installed) under the dash and it doesn't work either. I Dif notice that on the fuse block, the 3rd fuse up from bottom blows every time I install one. (Dont know if there's a connection) ? The fuse block says that fuse is for reverse lights (I have none) and for gauges (I have after market gauges) any ideas ?

 

Welcome, Jeff.
Congrats on the purchase.

Hazards, stop,and back-up have their own fuse from the panel.
maybe these will help.
Work on getting hazards working as they use the same path with stop lights.
Reverse are their own circuit, but you might unplug aftermarket gauges to see if fuse still blows, and if it does, plug in a single gauge at a time for singling out the bad gauge circuit.
