Indicator and light issue(cortina)

[mkvcortina]

Right so when i turn my headlights on in my mk5 cortina the left indicator stays on and doesnt flash without me having to even turn the indicator on via the switch. However it works fine as it should when the headlights are turned off, also the indicators flash alot faster when i use them with foot on the brake at same time. Also when my headlights are turned on low beam they are overwhelmingly dim, to the point where if there was no street lights you would have to use high beam if to see anything ahead... Any ideas on solutions to these problems would be greatly appreciated. Thanks in advance.

check all your earths sure to be the problem

dont suppose u could tell me where most of these earths would be on my cortina? also with the headlights only being really dim on low beam would this be a result of a bad pair of bulbs?

definitely an earth issue, had the same kind of thing on the belair...replaced/cleaned ALL earth contacts and now all is well

If it did it suddenly then also check your park and indicator bulbs on that side. One of them could be blown and the filament has fallen in a weird place and backfeeding to the loom.

 

But if the car has been parked up for a while and started doing it when you got it going then yes it would likely be an earth.

Look for any wires from the negative battery terminal bolted to the body or motor - clean up/scuff the body/block where they bolt up to and the terminal too. Try again and report back.
