Mo Murphy Posted September 25, 2005 Share Posted September 25, 2005 What should be the voltage across the batteries at tick-over ? Mines 15.2 v but I have a funny feeling that's not good Mo Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted September 25, 2005 Share Posted September 25, 2005 Old alternators = 13.8v Newer ones = 14.4v 15 volts is not right, no. Quote Link to comment Share on other sites More sharing options...
BogMonster Posted September 25, 2005 Share Posted September 25, 2005 Most 300Tdi alternators will give around 14.2-14.4V 15V is definitely into boiling battery territory money pit strikes again Quote Link to comment Share on other sites More sharing options...

Les Henson Posted September 26, 2005 Share Posted September 26, 2005 It's worth pointing out that a boiling battery can burst. Sulphuric acid flying everywhere doesn't bear thinking about. It might be worth borrowing a battery off of someone/thing until you get your alternator and battery checked. Watch out of the sides of the battery bowing outwards.
