hi guys, just wondering if you manged to sort this mate?
i have the exact same problems you describe, dimming and flickering lights, almost ready to die under full load with majority of elecs on, dials jumping like crazy and speedometer displaying dashes, engine warning light came on a few times (once for about an hour of driving)
i took mines to kwik fit for a free battery check after a friend had a multimeter on it, seems when i had elecs on inc demist and fog lights on the voltage at battery was down to below 10.1!! kwik fit confirmed pretty much what we thought and said new battery and alternator, although after reading this i feel i could be going down the wrong path and dont want to end up out of pocket (mind you it prob needs done on a 11 year old car anyway), and i had an issue orignally with a belt which tended to squeel on start up and hard acceleration or cold weather, now its pretty much not doing that anymore. strange.
so yeah just asking if you manged to sort this out witha replacement or checking cables etc as i have the time to investigate till payday when i can afford battery and alternator.
oh kwik fit also said the battery on my car is too small, should be in a fiesta or spmething apparently, i just bought this last month and been working solid so havent had time to look at it closely enough, think if i just bought the correct silver calcium would all be okay?
I did get it sorted yes mate, about 6 months ago i got a new alternator and told a garage to install.
It seemed to fix the warning light comming up, that never happens now although the voltage is 13.9 where it should be 14V. The belt was changed with the alternator but for some reason its not as good as the power steering is heavier straight after changing the belt as well as the volts on the low side however after 10,000miles later its still fine
