One other quick check you can easily do if the car is in a quiet place, is to 
listen when you turn the key ON. You should hear a relay click when the key 
goes ON and a second relay click about 1 second later.

If you have questions about whether this is happening correctly, look under 
the back seat, on the  driver's side. Mounted on the top rail, there will be 2 
relays, each mounted with a single screw. One of them has a ground wire 
under that screw head. Make SURE that screw is tight. That's the ground for 
the main power relay coil.
