Replaced the 12v battery, now the car won't start

i know, just grasping at straws

 

have you tested the continuity of the dome fuse?

 

obdii scanner available?
If can, jump start and read codes.

come on, i swear i just read this a few days/week ago.
I cannot seem to find the thread ( i will keep searching)

What about the fuse link/white cord at jump point under hood (maybe that was 3rd Gen?)
Possible that while connecting batt, something touched something? still thinking on that....wrench, something.

 

If the car powers up with any 12v source connected to the under hood jump point, then the problem is in the rear trunk battery connections, the fusible link assembly mounted on the (+) terminal, or the main cable that goes from the plug to the jump point in the engine compartment.

Results from checks listed in post 9?

Electrical troubleshooting is NOT rocket science, but it does require being methodical and it requires an understanding of how electricity works. It can also be difficult to perform without being there in person. It can be as simple as saying place a lead on a + battery terminal, but the do-er puts the lead on the terminal clamp. Even that simple thing can change the results. What is absolutely crystal clear in my mind can easily be clear as mud by the time it crosses the I-net.

There's a hundred different ways of checking this. You want a real go-no go? Take a 4 foot piece of wire and strip a half inch of insulation off each end. Jam one end in the crimp area of the big cable where it plugs into the + terminal fuse assembly. Touch the other end against a bare metal surface in the trunk. You should get a nice big juicy spark. Big enough that the wire may try to weld itself to the bare metal. Don't let that happen. If no spark or a very weak spark, then you have an open circuit/high resistance somewhere between the car body and the (-) terminal, or between the (+) terminal and the crimp, or between the two terminals on the battery. Voltage readings do not always tell the full story, as even a 100 million ohm connection will pass full voltage if no current is flowing. Yet any load applied to that circuit will cause voltage to drop to zero downstream of the high resistance.

 

congrats to you and @TMR-JWAP for coming up with the test!

 

Congrats!

Hope you get another 15 YEARS out of that new battery!
