My horns are not working, I've checked and get power to both so I'm guessing it's the horns themselves. I am thinking I'll replace them and take my time taking them apart to fix when I get around to it. So today's question is what do people suggest? I found this set that seems like a good option: https://www.godzillaraceworks.com/electrical/hella-supertone-horn-kit-for-datsun-240z-260z-280z-280zx-fairlady-z I know that the red will stand out, i could always paint them black.

Do they have good grounds? Have you tried to bench test them?

I put a set of Jaguar horns on my '83 Turbo back in the day. Great sound and always surprised people that is wasn't the typical Japanese "meep!" I wish I could remember what model I lifted those from.

Have you tested or tried to rebuild the horns?

The FSM describes how to adjust the horn sound and its actually very simple (screw on the back with a locking nut). Not saying they'll sound like a Jag, but altering the way they sound is possible. I believe each horn is set to a different tone.

I've been using a set of FIAMM air horns for about 50 years, very Euro and VERY loud!!! 😲

To recap...I was looking for suggestions on replacement horns for now until I get around to rebuilding the original ones. I ended up buying and installing these from Z Car Depot: https://zcardepot.com/products/horn-set-hi-lo-240z-260z-280z-510?variant=50610208964920&currency=USD&utm_source=google&utm_medium=cpc&utm_campaign=google%2Bshopping&gad_source=1&gad_campaignid=17820837536&gbraid=0AAAAADgHqXssZ64ffuRLMdHFQA1WVqNee&gclid=CjwKCAiA86_JBhAIEiwA4i9Ju_aM-ViE06tUtzcGp1fUrYiM7OyJd_3WeMCCfgkuDa7cRHrPUPNNsBoCRM4QAvD_BwE

They do the trick. Not sure when I'll get around to diving into rebuilding the original ones, though for now I can still drive around and let people know I there. :)
