Mk2 Fiesta indicator help

[adam73bgt]

Hi guys, trying to help my brother diagnose his Fiesta's indicator issue.

So basically his front right indicator light doesn't work at all, tried different bulbs and no change. If the right indicator is put on, the rear one flashes quickly and if the hazards are put on the rear right indicator flashes normal speed, but no flash from the front right at all.

Put my circuit tester on it with the hazards on and the bulb holder is giving out a reading of 3 volts.. so I tried cleaning up the earth contact for the indicator where it meets the car body as it was on a painted panel. But no good.

Any ideas on where to try next? the wiring diagram seems to show that the power for all the right hand side indicators can be traced back to a single point, any one know where this is?

Thanks in advance

I think you're on the right track. You've just got to clean things up and keep going back until you get to the problem.

Hi, the single point is likely to be the hazard switch. Because the hazard switch doesn't get used much the contacts fur up, so work the switch in and out a dozen or so times if no joy do it again. If you have any switch cleaner use that as well. A few years ago I had an Escort in with similar problem 12v behind the dash a lot less down at the light it turned out to be a broken wire in the loom which I found by unwrapping it a bit at a time an using pin in the croc clip on the multimeter pushed in to the insulation at various places along its length. Turned out to be the insulation had cracked due to heat in one place and let water in and corroded the copper wire. But my money is on the hazard switch.
