Horn Problem, Horn doesn't work Options

[capitolatim]

My car has a after market Carrera wheel. Horn tests good on a battery, power is there to the horn lead, ground test good to connector #5, when I ground the horn pluncher wire to the wheel the horn sounds , weak, and the wire sparks...any ideas?

I would be concerned that in your picture, the wire from your horn relay to your horn button is red. On my car and on the Pelican wiring diagram, the wire from the horn button, H, to the horn relay, J4, is shown as brown with a white stripe . What color is the wire at pin 85 on your horn relay, should be brown with white stripe? If it's the same red as at your wheel, check it's continuity to the horn button. If that wire is correct, then check continuity on the black wire with yellow stripe that goes from the pin 87 on the horn relay to power the horn. The brown wire on the horn itself is ground.

Thanks for reply, I don't think 1970's have a relay. Here's a photo of the contact ring.
