Workshop/Diary - Car Horn

27th April 2015 - New addition to complement the existing horn system and yes it is a gimmick, however at least I will be heard if it is required!

A nice warn day, just had a delivery of a new addition, a horn system   -  5 Sounds Loud Horn Siren Police Fire Warning Alarm Speaker Car Boat Van Truck, ok it's a gimmick, full 100W with 300db enough to makes sure people know you are there. Connection is normally straight forward with red and black for positive and negative battery or live feed
connections  and an extra wire to the microphone and sound generator hand piece. (supplied and just clicks together and connects to the horn).
I decided to install the horn under the bonnet, (hood)on the offside front wing shell, mainly for weather protection and easy wire feed access to inside the
vehicle. By lifting out the o/s filter giving access to the master brake cylinder and a large rubber grommet giving access to inside the cockpit. The red and black wires are short so an additional set of wires are needed to extend into the drivers area. One can issolate the earth under the bonnet, however I decided to earth the black wire inside under the dash on the chasis. The red wire was routed to the cigarette lighter with an inline fuse (10w small blade) and scotchlok. The hand mic has an on/off switch. Tested briefly and system works ok.
