Gents, I have a similar problem with my 2001 4x4 Morgan 25000 miles on the clock ( true milage ) I have recently fitted a new fuel pump, as the one in the tank stopped working so now the engine is running well, all dashboard light working all gauges working, But only the main beam flash works when the indicator switch ( left hand side of column ) is depressed etc, when i depress the rocker switch for the main lights ( right hand side of the steering column on the dashboard ) the lights do not come on, No indicators work no flashers work, the wipers work but no external lights work, not sure if the break light are working when the pedal s depressed, I'll get her indoors to have a look

any idea's what the problem could be, all fuses look good three new relays fitted from Brands Hatch Morgan
