Ive tested the volts from the back of the alternator and they are 14 but when i test the battery only 12 are going in. Also ive lost the battery light on the dash does anyone know what the fault is. Thanks Mike

have you test both while the car is running ?
as the wires are connected the volts should be the same , there is no reason other then a small earth short for this volt drop.
the volts seem right if you tested the alternator when running and batt when off .

i tested both the batt and the alt with the engine running thats why i cant understand the volt drop maybe there is some coroded wire somewhere not letting full voltage through. Ill have another look and if i cant find anything ill get a new batt cheers for the help.

This saga is not over though. Car was not used for a while and I noticed that battery was struggling to hold charge. Seemed to be all over the place - voltmeter jumping off the scale!! Went to an an auto electrican and changed the voltage stabiliser in the alternator. Prior to that it had over charged the battery! So, another new battery!
Last bit - promise - and I think this is key! Change the loom from the battery to the alternator. Any good auto electrican can rig one up - has made a HUGE difference - explained why I was getting through batteries - they simply were not getting the juice. I think there is a market out for new looms as the wiring simply degrades in a car 20 years old
Good luck
:wink:
