A while ago I posted an appeal concerning the lack of charge on my 90. The warning light was extinguishing as normal but the battery was slowly going flat. I checked the charge voltage and it never got above 13.2. It was suggested that I clean the alternator connections, which I did. Charge voltage is now 14.2 max. Still quite low but it seems to be enough to keep the battery topped up now. So, thanks for all the advice, saved me £70 for a new alternator.
Bad charging update

14.2 is bordering on too high - 13.8V and above is more than sufficient to charge a battery and anything much above 14.2V tends to boil all the eletrolyte off.
