Hey everyone,

My friend recently passed and I inherited his 06 Toyota Matrix. Was running really when and then was parked for about a week. When I went to start it again it is completely dead. Like it has no battery kinda dead. When we hooked it up to my moms car with booster cables the head lights came on but that was it. Found the 100A fuse was split so we bought another and just replaced it. Still absolutely nothing though so I'm at a loss. Does anyone have any tips at all to help diagnose the issue? I've done a decent amount of my own mechanics but the electrical side of things has always eluded me.

Thanks!
