MG MGB Technical - Electrical Problem

Hi,
My 1975 MGB just failed its MOT on an electrical fault that has the garage confused.

1) Sidelights work OK
2) Switch on Dip or main beam - no dip or main beam work but all indicators come on solidly.
3) Switch all off, operate hazard switch, only headlights flashing.

As you mignt expect all worked Ok yesterday on my pre-MOT checks,

Any clues appreciated.

Thanks

It sounds like when you find the short in your unfused headlight circuit, you will probably have your answer. Look for burned/melted wiring, most likely under the dash between the headlight switch and the flasher.

You can also try removing the flasher unit and see what happens.
