Horn installation- sparking at ground?

1410 Views 4 Replies 5 Participants Last post by  Mort
Im installing an oohga horn and have one terminal of the switch going to an "add a fuse" (size 10 fuse) and the other terminal going directly to the horn. There is only the one singular wire coming out of the horn.

I am mounting the metal plate/base of the horn in order to ground it, however before I bolted it on all the way I barely touched it to the grounded bolts just to test the horn and when I pressed the horn button I got sparks coming from the grounded bolts.

Whats the issue here??

The poor ground is the problem. It took less current to jump the air gap than to sound the horn.

what he said, clean and tighten that ground
make a good connection and you wont have sparks.
...that, and disconnect your battery when you're working on anything electrical.
