Noticed my warning lights came on and the charging volt meter went up to 17 volts. Im told it might be the regulator on the alternator. Could it be anything else or is it more open wallet surgery !

Id check with a multi meter just to make sure but it will be a regulator issue. Alternator will need to come out and be stripped down.

I was told 14 is the top limit

Calcium Battery's often need up to 14.8v to be charged correctly. But 16v is defiantly on the high side and you will end up with over charging and boiling of the battery. Shortened battery life and other issues.

Would 28volts be to high on a 24v Nissan Safari!

28 volts equivalent to 14 volt on 12 volt system, so all good.

Ok my year old batteries have the red thing showing up on them, what checks can be done to see if it the batteries or the charging system thats playing up.

could be regulator could be a rotor fault as well. the alternators are cheaper to fix than nissan ones. also cheaper to rep;ace than nissan ones

for a calcium battery 16 volt is ok they need high voltage you should rev it and see if it goes even higher at higher rpm that would indicate regulator fault if it went higher and higher with more rpm

this is true but however his batt light is on and the set point for that regulator is 14.4 so clearly a fault

Ok cheers for the info, the batteries (SuperCharge golds) are not even half way through a 24month warranty, 28volts is the max it goes to, sits just above 24volts at idle. Is there any way to test a battery!
