All,

This is in follow up to my previous posting on the reversing gear in my Santa Fe diesel.

I am trying to activate the Horn. When I insert a "D" size battery (either up or down) the "whistle control" from the Transformer doesn't activate it.

There is also a 9V battery connector in the battery compartment, that may have been an "add on" from my deceased brother. If I attach a 9V battery to it, the horn blows off!!

Any advice on making this all work would be appreciated!
