G'Day,

Got a Volt /Multi Meter?

What Voltage do you have on the Battery when the car is running?
You should have 13.8V to 14.2V or so.

When doing this also check the voltage at the Alternator.........Oh! You might consider to Charge the battery before you start.

Then, Disconnect the Battery Charger

If the Battery Voltage does NOT increase to the 13.8V to 14.2V then the Alternator is perhaps cactus.

If you have the 13.8V to 14.2V at the Alternaton;
Then you have an Open circuit between the Alternator and Battery .........BIG Fuse or a VERY BAD Connection.

My Money is on the Alternator.
