Electrical Issues

ok in my R31 im having this stupid stupid problem.

i turn my lights on, tailights come on fine, headlights a no-go, same with high-beams. aswell as this when i turn the headlights on my windscreen wipers come on, indicators all come on at once and stay on very dim, my dash tacho and speedo go to zero, and all other guages have erratic behavior, powershift light and door ajar light come on, and also the volt light. when driving, it also kicks down the auto to a lower gear....

similar thing happens when i use my indicators, the said above side effects happen indicators work fine! but what makes this worse is the auto then fluctuates between gears as the indicators blink O_O.

its giving me the biggest headache ever, especially seeing as this is my only car at the moment and i cant drive it at night. iv pulled the dash out and checked all connections. pulled every fuse from under the dash and checked for blown ones, checked all of the grounds in the engine bay that i can find, checked connections to the headlight elements etc. im out of ideas

anyone else able to shed some light?

I suspect it might have something to do with a bad earth. I note you have checked earth connections - have you cleaned the battery earth terminal?

Have you done any work to the car recently? Something that might interfere with wiring? Drilling holes, etc?

the only thing i have done was pull the centre console apart to change the globe in the gear selector. it used to happen off and on when i went around corners or over bumps, and now its just like it all the time... i was thinking a bad earth too, but where? :S

but where? :S

EXACTLY!

But it may also be a couple of wires have rubbed through and are shorting across each other.

Good luck finding it!
