- Hi All, One of my winter projects is to determine why the horn fuse in my TR4A keeps blowing. I had installed a Advanced AutoWire harness during the restoration. The harness contains a 20 amp fuse fo

- ...not sure of the coil spec...but just for a reference.... a normal buss style fuse marked 'rating' is the spec holding current. (should not blow) It can take 10+ minutes to blow at 25% over the spe

- I read through my Advanced AutoWire manual just now and it specifies a horn circuit max. current of 15 amps so I will need to find some horns that have a coil resistance of about 1 ohm if I donā??t c
