Parked car up for month as gearbox went. Sorted that out but now the front right indicator not working. I've tried swapping bulb holder with otherside no luck put circuit breaker on no power getting to bulb holder or same colour wires on indicator stalk yellow and green and yellow I've tried tracing wire outside for corrosion all good up to expansion bottle and still no luck
Car: Peugeot 206 Variant: 1.4 petrol manual Year: 2003
Only 0.4 volts means a wiring fault/high resistance.
I've seen French wires green and corroded inside the wire.
so recheck at the output at the stalk switch then on from there.
Easiest way is with an indicator bulb in a holder and jump wires,
one to ground and the other on a pin so as to be able to stab the insulation through to wire and see if it lights.
If it doesn't at the stalk then the stalk is faulty.
if it does the it's a case of move along down the wire until the test lamp doesn't light and the fault is between there and the last place the test light works.
Tried another full indicator unit still same problem misewell try replace wiring loom back to fuse box can't think of anything else and can't see fuse box being it fault for one indicator when they usually go in a pair
Like I stated I've see and repaired wiring that "looked" absolutely fine eyeballing it but inside the insulation it just goes green powder.
High resistance no current.
I'm sorry I can't be more helpful my laptop with the Peugeot wiring diagrams isn't working but I can tell you Peugeot usually don't go by wire colours,
They go by Alpha numerical markings at the terminal ends.
So you may not be testing the right wire.
If you could get it plugged into Peugeot Planet diagnostics there a program you could run whereby ALL electrics can be run and tested on a laptop.
A global scan is what I'd run first then operate the indicators via the lappy.
Net test results would be if the indicators run on P.P then the wiring isn't at fault and so on.
