Horn really and horn wiring

#1 Post by Tim Menefee » Sun May 27, 2018 10:47 am

Hi, I'm trying to put horns back into my 59A. The original relay is there with 5 wires. Two red go to fuse box. One brown goes to horn button switch and two black that should go to the horns. I assume...

Is there anyway to test the relay?

There are two + wires by the horn that connect. Why two wires?

One black that I assume is the ground return?

On the horn does the + and - have to go to one side. Ex. + left - right?

Thanks for any help,

Here is a circuit diagram for the horn circuit in a 356C, I assume should be similar to your 59A.
This diagram appeared in the Registry's magazine.
Yes you can test the relay.
