Clk, ltr,crtsy fuse
Hey everyone, I recently acquired a 77 corvette a couple weeks ago with the clk, ltr, crtsy fuse pulled. I bought one and put it in when i suddenly started hearing a clicking/knocking coming from behind the left rear wheel upper. Almost like left signal light is on but it’s not and it doesn’t seem to be the power antenna. Car is not running and Keys are not even in ignition and I have no clue what is electrical in that rear left wheel area. Maybe fuel gauge? I figure this is why the fuse was pulled and never put back. Any thoughts?

Why don't you just try and unplug the power antenna anyway and see if the noise goes away? There's nothing else in that area of the car from the factory and without the courtesy fuse you don't have brake lights either.

When the alarm horn fails it makes a dull thud kind of noise, and as the alarm cycles, it will go , thud, thud, thud. Do you have a early or late 77? Is your alarm switch in the left front fender? Or built into the door switch?
sounds like your alarm is going off. The horn is bad and makes a thud instead of a beep. (Common).

Lay on the ground, head just behind the rear wheel look up. See horn bolted to the inner fender well. Put your hand on it when it's going off. You will feel it.
