Just that yesterday the needle was sitting at 14 and a half?normally its at 12 and a half.
What does it mean when the car does this?is it actually compensating for the loss of battery charge?Or does the alternator give a standard level of charge whatever the situation?

Many thanks
Damien.

No voltmeter in 93 / 94 instrument cluster..., sorry

adminisTerTurbo

climate control can display it

As more amperage is demanded, the voltage drops. Lowest I've seen with the engine running is about 13V. High amperage drawn by headlights, A/C (radiator fan comes on), seat heaters. As long as the voltage is above about 12.5V, the battery is charging.

Same here. Usually right about 14 volts and drops to 13.5 with heavy load.

Damien,I experienced some issue before.You may check the connector from the alternator to the Starter.there'll be the big black wire.I got loosen on the starter jumper.So there's insufficient charging to the battery.and when the engine is hot.my starter was sound very weak and it was back to nornal when it has been sitting for an hour.I figured out that all the issue was from the loosen jumper.there was some
spark on there too.worth to try.

PS. someone's here been told me that the voltmeter on the IC has been shown less than actual around 0.5V

Thanks Pop will check that out....

Ignition on: a hair below 12v

Cranking: 9v with the needle swaying a little

Cold idle: 14v

Heated seats & defrost make the needle move a little bit. 55w xenons low beams make the needle wag a little more so. 55w low + fogs on leave the needle at a hair above 12v on the gauge.

from yesterdays 14 and a half?hmm will have to keep my eye on it.
Thanks for all the info guys,put my mind to rest to see what we all are getting.

At ignition,I have 11.8-12V too.It should be the problem when it's down too 10.5-11V
