ross501:
could anyone tell me where the 3 wires go off the back of the alternator 1 to the dash 1 to the starter this leaves a third

problem being the landy is not charging and the light in the dash does not work but the bulb and the wire beetween the alternator and bulb are both fine

mark.yellow.series.3:
usually,
the large terminal is connected to the battery, more ofter via the big terminal on the starter, this is what puts the charge in the battery.

small terminal that goes to the dash light provides the exitaion to the alternator, with out this the alternator woulndt give an output, and also indicates if the alternator is working ( but not always :wink: )

the other terminal is probibly an output to run a rev counter.

ross501:
the third wire just floats around by the starter motor on mine dont think its ever been connected  but the light does not come on and it does not charge

ian_s:
where does the 3rd wire link to the alternator? in the same block as the other 2 or somewhere else?

if the light is not coming on at all, i'd check that the wire from the starter motor is delivering voltage to the alternator, then check the same on the smaller cable that comes from the dash. (with the ignition on, obiviously)
if either of those dont have 12 v at the alternator, i dont think it will charge.

ross501:
it links to the same block all the wires are ok tested them just the alternator got very wet and was wondering if this has killed it now
