hi all, new to the website and in need of some advice (usual story i guess!)
my 82 mk1 fiesta is beginning to beat me! (goodness knows what i'd do with the electrics of a new car!)
the battery charge light is coming on faintly. so I check the battery earth (the fault last time!), then the battery volts just over 12, then the 2500revs volts - around the 14 mark. so i begin to get confused
the next thing i notice is, the higher i rev, the brighter the light glows.
also, it hesitates on initial start-up (as does the rev counter )
i check the volts from the blue lead from the alternator to the instrument cluster - showing the charge from the alternator fine. i check the earth from the cluster - fine.
as i understand it (could be wrong!) if the volts from that blue line go lower than the battery volts - it lights up to warn you. so how come it's getting 14v and still lighting up? a short circuit?
that's about as far as it got - any ideas much appreciated
