Morris Minor Owners Club

Ive noticed yesterday that when my lights are on,the left headlamp is dim and also the side lamp lights up the indicator instead.
I wonder if it is an eathing issue if anybody can help please.

Bad earths are the cause of a lot of car electrical problems.I'd work my way through the lighting ones first of all, taking the tags off, cleaning them and the bodywork under the fixing.Back to bare metal and the reassemble with a protective coating,
Vaseline / grease / coppa ease whichever you prefer.
After that check with a multimeter that you are getting a "full fat " 12 volts supply from the battery,Red wires for side lights.The bullet connectors and terminals may need a clean up.

It IS an earth problem at that headlight.

Both spot on,I cleaned all terminals including the earth today and all working correctly.
many thanks
