The Electrics

Assuming that the components are not rusted out, or that the coil is not burnt out, normally all I do is clean, repaint and re-chrome the parts as required. There is a set of contact points which can be seen in the photo to the left below which need to be cleaned and then gapped properly on reassembly by adjusting the small screw on the back of the horn enclosure. The horn works by pulling in the hammer till the points open. The anvil acts as a stop for the hammer. You can slightly adjust the tone by threading the anvil in or out from the rear of the horn, although the range of adjustment is very narrow. The most important point is to ensure that however you adjust things, the contacts are actually able to open and break the circuit as otherwise the coil will just burn out. When bench testing these, I use an ohm meter to check that I am starting with an open circuit before applying power, and then adjust the point gap till the horn starts to operate. On this horn, I used stainless steel screws to reattach the re-chromed cover, and while it isn't 'as per factory' the horn does work well.
