rear lights + indicators interacting

[technicalfreaks]

hi all....
my problem is this...
when using the indicators(or hazards)
the rear lights + the reg light flicker in the opposite pattern to the indicators...

any ideas on where to begin ?
iv been told it could be a possible earthing problem.....
but it sounds like a voltage drop so could be a dodgy fuse ?
or even a dodgy connection with the bulbs ?

Check the wires are all in properly and no bare wires are touching each other. Would seem like a locgical step to me

It'll be an earth problem, the make of car would be a help, check and clean the wiring block to circuit board.

If I remember I had to make an earth wire for a 306 rear light.
It's the block that goes on the rear light unit, pull it off and see if there's any corrosion,

hi, iv checked all the earths associated with the rear lights, and indicators...
checked the wiring blocks, checked the fuses...checked the bulbs and holders...

cleaned it all up, some of the bulbs had a bit of corrosion on them....

AND IT IS STILL THERE !!!

i hate nigly electrical faults...
