Battery light and stop light 182

[ABirchmore]

When the car is on full lock either side it squeaks what sounds like a squeaky belt? Also the Stop light and battery also come on when this happens? We also get the fog light flickering when braking as well? Sounds to me like typical French electrics but if anyone could help narrowing it down that would be great

Fog light is corroded earths on rear night terminals

stop battery is probably the alternator or aux belt
get that checked > dont want it to fail & ruin engine

Check the aux belt and pulleys ASAP. My alternator pulley came lose, snapped the aux belt and took the cam belt with it. Needed a head rebuild to fix.
