One of my winter projects is to determine why the horn fuse in my TR4A keeps=
blowing. <br>
I had installed a Advanced AutoWire harness during the restoration. The harn=

tion. I went through the wiring harness and could not find a issue there so n=
ow I am looking at the horns themselves and that is where I need your help. I=
