Help I need my horn to work in order to race!

I guess the real question here is why isnt your horn working? Putting that effort in the installing a new switch may be a moot point if you havent tested the system well enough.

Do you know if the horn works at all? All you need to do is apply 12v to the connector at the horn in the drivers fender. If it/they work then there is a relay that would need to be tested then the actual switches in the wheel or if you have a early fox its in the turn signal lever where you push it in the column.

I would fix the factory set-up. It is a very simple deal.

I know it is in the NMRA rules, but I have never had them check my horn.
