Side lights problems

[31449]

I am rebuilding my 1971 stag after respray and the following faults have appeared-the side lights have stopped working , they were working yesterday , the indicators are flashing really fast , the main beam lights are working ok .
I have checked the fuses and are all ok.
Any advice appreciated

All earths seem ok and were working yesterday.Plus the rear indicators are fine and are on same earth at rear.

Check tall he earths again at the bullett connectors.behind the radiator grille. They are almost certainly a bit corroded.

If you get voltage to the red wire that feeds the sidelight unit but when connected it drops to zero then there is a dirty connector somewhere in the circuit.
