Checking the alternator is charging the battery

[Black_Potato]

Having recently done quite a bit or rewiring including replacing the Dash etc.. I want to check the alternator is charging the battery.

Is there a simple place I can test with a volt meter to confirm, or maybe another similar test.

Cheers

Stick your volt meter on the battery when the engine ia running. Should be somewhere between 13.8-14.4V

Get a multi meter, check the voltage at the battery, should be somwhere around 12.5v

Next start the car, repeat the test with the car idleing. The reading should now be somewhere around 14v. This way you are checking the alterator and the wires in the charging circuit.

That was obvious, there was me looking for something complicated


Thanks.

As you've done dash work, make sure the battery light is wired up otherwise it won't charge at all
