Alright here it goes.
I put on these horns from a 92 GTI so my gurl an I could be heard better.

I first started having issues with this switch and instrument cluster after our last rain.
At first I had turn indicator lights in dash dimly lit while riding and they would go out with the clutch disengaged.
Then I noticed after using the horn my horn/digitals/brake light fuse blew.

Tonight I went to use my horn but nothing. BUT, the fuse did not blow like before. Instead all lights dimmed while pressing the horn and the horn sounded like it was trying to make sound but just for the first initial press of the button and was very muted.

I thought it was a bare or compromised wire insulation but all checked out. I do have a suspicion though that I may want to upgrade the wiring to the horns. They (wires) felt very warm and flexible(more than usual) once I got home to inspect them.

Any thoughts on this would be much appreciated. I am not sure if it is a switch/wire/horn problem just throwing out there what I have noticed.

you need to run any horn other than the stock horn through a relay

I used the stock relay (if there is a stock SV relay?)and since this is now a 2 horn setup(2 notes) I just used the factory VW jumper from horn 1 to horn 2 . Do I need to upgrade the relay?

The horns are wired like so.
From where the OE SV horn wire plugs into the factory horn I plugged in horn 1.
From horn 1 to horn 2 I used a jumper wire just like 99% of all vehicles on the road. I hope this helps.

If it's blowing a fuse, the circuit is being overloaded somehow.

Time to break out the wiring diagram and trace the circuit from the horn, back thru the fuse, and beyond to see all the things in the circuit that can be causing the problem. Bust out the multimeter, and start testing stuff. Break the circuit down by checking sections of it at a time with the multimeter until you narrow down where the problem is. Then, once you pinpoint your problem, fix it.

that is your problem right there. YOU NEED TO RELAY THAT HORN. Search the forum for relay there are several threads recently addressing this issue. If you are not careful (or if it isnt too late) you could blow the switch itself.

Thnx. I thought the SV came with a relay already. I'll search around to see what I can find. If I only knew...........
I love the horns a lot and wonder why just now I am having probs. they have been on from the first week of its' life.

This is true. Run it thru a relay and be sure there is also a fuse inline to protect everything.

It's not too hard to wire up something like this.

Like a SPDT ? but any idea on fuse link rating? I could look up the vw ratings for the horns,unless there is an "industry standard" I am not aware of?

I agree it's not too hard to wire up I just had no clue that a SV had no horn relay.

I will search the saturn forums for a pin-out diagram I used for the SV. It is all basicly the same thing really. run a hot line to the relay a ground line to the relay, a line to the stock sending line then a line to the horn. sepending on whether the horn is hot signaled or ground signaled will depend on which line will go to which pin. I believe the headlights are ground switched where the horn may be hot switched. awe if I was in my room I could tell you right away since the manual is there.

This looks like the usual wiring for horns without using 87A (secondary horn) http://forum.svrider.com/showthread.php?t=94565&highlight=horn+relay

Saturn manual??? I know German wiring is color coded completely diff. than domestic and a lot of Asians. But I can get the gist of it anyways.Thnx a lot I'll have to get a relay and link it tomorrow. H#ll for a while a lot of car manufacturers were using the Bosch stuff so it's prob. all the same just know your color codes.
