The Stovebolt Site Forums The Shop Area The Electrical Bay Removed ammeter, wire to horn

Hi there,

I'm in the finishing weeks of my restoration project of a 1954 GMC 100 truck.

The wiring is almost done. I will remove the ammeter and put in a volt meter.
Therefor I can simply connect both wires form the ammeter (alternator to starter).
But now I need a the cable from the + side ammeter to the horn.

Can I simply add this one to the already connected cables?

Hopefully I explained good enough.

Thank you very muc!

Are you using the stock fuse block ?

If your feeding the horn off the ammeter wiring I would add an in line fuse for short protection.

Added protection some might add a 30-40 amp fuse in location #3 on the diagram.

Originally the horn wire was connected to the battery side of the ammeter. All of the rest of the wires were connected to the other post.I have always wondered why the horn wire wasn't put on the same side of the ammeter as the rest of the wires. I would just wire it to the closest terminal which is on all of the time.
I have also always wondered why the ammeter isn't called an ampmeter. (The origin is likely to have come from an Arizona engineer is my guess.)

Thank you all for your help!

I have an alternator, 12V, positive ground and indeed rewire from a harness kit.

I think the problem is obviously solved because I use a horn relay.

Thanks again!
