Toyota Matrix

2003 matrix. Brand new battery just ran diagnostic (no problems)



Ran car for 20 minutes parked for 15 ran for 10 minutes parked for 20 minutes. Wold not crank back up for 3 hours Any ideas?

You may have a short somewhere. You need a competent mechanic to do an electrical SYSTEM checkout. Whoever did your diagnotic obviuosly missed something. I’m assuming that the brand new battery has been checked out and holds a chrge.
