I should mention that all the chassis earthing points (body/g'box/subframe) have been cleaned for good contact. That was my first idea. I'll have a check with the multimeter for any parasite currents. (I don't think that there will be any, the is feck all electric in the car)

Could be that fancy watch you keep connecting up to it thats flattening the battery. Balfes are dear, but they are also the only ones I know in Dublin. I use a crowd in Naas beside RFL that are cheaper, but not that much so. How much is an alternator online? Might be the way to go. Do GSF do them?

Looks like I have a bit of detective work to do. Lastly it's hardly normal for an alternator to give out 15+ volts? I always thought the range was 13.4-14.6v

Are you getting 15+ volts from it?

If the battery is weak in the multi meter, it could be over reading the voltage. I've been fooled by this before.

Seen that one before as well.

As in the video, on occasion at idle you get 15+V from it.

Battery is fresh enough on the multimeter. Its a Lab standard Fluke multimeter so its accurate is you can get.

EMR off Dorset St quoted me €100 to rewind my own. http://m.goldenpages.ie/detail/0dd3d...a5b74f0d290923

Maynooth Auto Electrics wanted 90 euro for a reconditioned one (you didn't need to give them one...)

If you gave them one, they would swap out the dud parts and refit it for less then the 90 euro (though he said if everything needed to be replaced that it would cost 90 euros)


Further Edit:

I checked earlier for any parasite currents. No draw on the battery when the ignition is off.

There should never be readings of over 15v, regulator problem still seems the most likely cause, especially since its a very basic charging system.

Fortunately the voltage regulator is a cheaper to replace, so I'm going to try that first.

Taking the thing off requires removal of the inlet manifold which is a pain. Ahh well....
