6 volt horn relay
It appears my horn relay isn't working, Power going in but nothing coming out. I see where our vendors sell a 6V horn relay, but it doesn't look like anything that's on my car i,e. the original horn relay. Any idea on how to convert/wire the new relay if your car still has the original like mine?
Thanks,

Re: 6 volt horn relay
Bob, there are probably several of the original horn relays available from some of our vendors like Klasse 356, The Parts Shop, etc. and in the Samba.

Re: 6 volt horn relay
First, thanks to everyone who has replied. I've checked all of the usual sources (Stoddard/ NLA, Pelican, Sierra Madre and others) other than what's on Ebay that look to be very well used, the only new ones available are configured differently than the original. Thanks for the suggestion on 356 Electrics, from there I can probably figure out how to connect the new style relay though it's not immediately clear how to do that.

Re: 6 volt horn relay
I have removed the case and only had to clean the points to restore the function. if it clicks with the horn ring, the coil is working and its just the contacts. If no click the try grounding pin 85 and see if it blows. if so its the ground circuit to the horn ring or button.
They are a pretty simple circuit, hot all the time from Fuse 2 and a ground in the steering wheel, Power 6V to 86 and ground to 85 should activate the coil. 86 is the one with Two red Wires one large from 30 and one small to 86, if that works clean the contacts in the relay. The horns are one of the largest current draws in the car and the contacts get burnt and corroded.
PM me and I can walk you through testing and repair, or I can show you how to replace it with a new style hidden relay leaving the old can in place for looks.

Re: 6 volt horn relay
John,
Thanks, after I grounded the brown/white wire, (per the trouble shooting procedure in the 356 Electrics) and the horns went off I determined it wasn't the relay. It turned out it was the connection of that wire to the wire in the steering wheel. When I tightened up that connection the horn functioned as it should.

Maybe but it doesn't make up for all the times I have been cursed by those same gods.

Re: 6 volt horn relay
Mine was in poor shape, I tried to fix it, but as it turned out the windings were also rusted, so I could not get it to work, and ended up getting a newer style, and making doing some jumper wires into it, so tht I did not make any cuts into the wiring harnase.
picture shoes before and after the rust..
still no work..

Re: 6 volt horn relay
Ouch! mine has been pretty much insulated from the elements in the 33 years or so since I've owned and restored it. But I spoke too soon, the brake lights aren't working now. Arrgh!!

Re: 6 volt horn relay
Bob - well, the good news is that there isn't a relay in the brake light circuit.
