What is this silver box by the fusebox? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hello again!

Working on my daughters 67 C10 some more. Been having some electrical issues, but think I have it narrowed down to the battery (Which was new! lol)

I do have a question... When I first hook the battery up, this silver box clicks. Each time I pull the neg cable off, then put it back on, it clicks. What is it, and should it click everytime I hook up the battery? It is to the right of the fusebox on the firewall. Thanks!

That is the relay for the horn.

Is it supposed to click when I hook up the battery? The horn button in the steering column isn't hooked up, it has a smaller aftermarket steering wheel on it with no horn, I assume the wire is just "In there" somewhere in the column....

The wire may be grounding inside the column. If you are not using the horn you can unhook the relay.

From the look of the wiring someone may have installed a remote horn button. I had horn issues ended up the turn signal lever retaining screw in the steering wheel had come loose so I had to pull the wheel to tighten I live in a big city definitely need my horn.

The previous owner had did some "Creative" wiring.. lol.. So I assume the clicking means the wire in the column must be grounding? I want to hook up a horn in the future with a different steering wheel, but for now won't be using a horn. So I can just unplug it without it affecting anything else till I can get to hooking up a horn button?

Yes, you can unplug it. If the horn was hooked up it would be blowing all the time. (if the horn itself actually works)

Is this a NO or NC relay ,, could account for clicking when energized

**biketopia** · 07-24-2017, 11:24 AM

Should be normally open
