Yeah I've tested the battery of tests with alternator. I've tested the starter. I'm still having issues for when the vehicle is running if I turn on the lights the car shuts off. I've tested for shortages in the amperage I found out that the ACC backup fuse was drawing power I pulled that once I turned on the lights it was fine for 2 to 3 minutes I turned off the lights turn them back on the car shut off again. what do I need to do?

Hello,

This sounds tome like you have a parasitic draw issue and it has killed your battery. Every time a vehicle battery is run completely dead it loses 1/3 of charging capacity. So if you run the battery completely dead 3 times, it is basically shot.Can you please take a voltage reading with a Digital Multi-meter [DMM] across the battery terminals. If you don't know how to use a DMM,here is a link below explaining how:

I have also included in the diagrams down below a guide on how to find parasitic draw in a vehicle. Please take the voltage reading and go through the parasitic draw guide and get back to us with what you are able to find out.

Thanks,
Alex
