Hi there! 

I went driving yesterday and noticed my ABS light and my battery light both came on when my car was at red lights or if the rpms were under 1.5k. Whilst driving home, my lights dimmed, both my speedometer and rpm gauges bounced up and down and the car died. When putting the key into the ignition, there are no dashboard lights, and when trying to turn it over there is no click from the battery, no sound, no nothing, completely dead. I tested the battery, and it had 12ish volts to it, and sparked when putting jumper cables to them. Not sure if it's an alternator issue, or maybe something deeper.

Any and all help and advice would be greatly appreciated!

Thank you!
