Battery advice


Recommended Posts

Hi all. Looking for a bit of advice.

The battery warning light has jut come on on my jag. I turned the engine off then back on And the light went off, until I started to drive and then it came back ok. I have just checked my battery and its 75ah and I think I actually need a 80ah. Would this be the reason for the light to come on the dash?

One thing to think of as well Adam. Check your alternator belt is the correct tension. If it's slipping, that will also cause the warning light to come on.


The intermittent nature of your problem would lead me to check that first. Also, check the alternator is giving a good solid 13.8 volts.
