from the chassis: protect the un-insulated wire portion with insulating tape
ffff)))) If the engine stop electric wire is properly insulated from the chassis but,
though the petrol engine turns, it doesn’t start, try to disconnect the engine
stop wire: if, after disconnecting the wire, the engine starts, proceed with
the replacement of the main electronic board S

board is not available, to go on working it is possible to leave the engine stop
wire disconnected. This means that the engine stop wire will have to be re-
connected to stop the engine at the end of the working session
