Technical Help headlights fuse

[mk1Punto234]

right, when i turn on my headlights one of the 10 amp fuses always blows meaning the left headlight doesn't function no indicator sidelight nothing, while the right one works, i have plugged the left headlight into the right sides connectors and everything functions correctly, so my thinking is that it is to do with the wiring on the left side, also this started happening after a few drops of water got into the left headlight but this has happened before with no issues and i have removed the water and sealed it back up

Check that its all grounding properly..

A bad or faulty earth can easily blow a fuse

i would say he actually has the opposite problem
somewhere in the light the live is grounding causing the fuse to pop
it might even be the headlight bulb filament bulb causing this or a high resistance due to water ingress of the light so live is finding an easier option

That would be my guess, too. Well worthwhile visually checking the cable(s), also the connector to the headlamp itself, which can overheat and turn to (something which looks like) coal.
