Yeah - another horn issue - 1973 914 Options

[dhempy]

Hello everyone,

I need some help tracking down a horn issue on my '73 914.
I have had the car 20 years and can't remember the last time the horns worked.
I decided to try to fix the horns before I installed a new JWest fuse box.

Troubleshooting procedure

1. Orig horns did not work with 12v - bought new Hella Sharptone Hi/Lo twin horn kit
2. Installed new horns, ran a jumper from pin #30 (relay out) to pin #87 and the horns work. (And they sound great too). Does not work with the horn button yet (Ign on)
3. Ordered a couple new relays (just in case). I manually checked the old one(s) with a 12v small backup battery from my garage door opener connected to pins #85 & #86 on the relay - it clicks then i checked continuity at pins #30 & #87 - all good. Relays work but the horn still does not work (and no clicking at the relay)
4. Here is where I am stuck - pin #86 should have 12v (Ign on) and does not. I have continuity between #86 and fuse #8 but I do not have 12v at fuse 8 with the ignition on. Swapped fuse and checked continuity too on new fuse just to be certain.

How is 12v fed to fuse #8?
What should I do next? Am I missing something?

I want to get this resolved before I throw another variable into the mix by installing the JWest fuse box. All comments about this replacement fuse box are welcome (IMG:style_emoticons/default/biggrin.gif)

At least the horns look cool installed
