1951 dodge

[acdeegillnn]

I restored a 1951 dodge Meddow brook . I did everything over.including the wire harness . i am having a problem with getting the horn to work? I understand that it is a positive ground system. I have the wire gran and have followed that . I thought it was the relay ? I purchased a new aftermarket relay and have tried to get it to work and have tried it every with way but to no pervail?  The body has power to it sush as the cowl and radiator support when i touch it with a test light I would think  that this is meant to be with a positive ground system ? If I touch the wire from the horn to the neg cable it works? But it does not work with the relay? Any help from someone with experiance in this positive ground system 

 

thank you

Just something to consider.  Is there 1 wire to the horn?  If so then the horn probably needs to be grounded.  See if the bolt and bracket for the horn is making contact with bare metal.  After a restoration when everything gets painted this is a common problem.

Have you resolved this issue.  If not, I may be able to help.  I rewired my horn system recently and found many unexpected problems.
