One of methods of search of a point of short circuit consists in getting a safety lock and to connect a control bulb or the voltmeter to plugs of connection of a safety lock when all other elements of electric equipment of this chain are switched off. In a chain there should not be a tension.
Move wires here and there and watch a control bulb.
If it lights up, means, somewhere in this area short-circuits one of wires, it is probable in that place where isolation was wiped.
The same test can be carried out on any other element of a chain, including the switch. |
