Dead 2001 SL1
 

I am hoping someone has some advice..

I have a 2001 SL1. The battery went dead and I replaced it. Now the whole car is dead. No lights, no horn, no anything. I tried to jump it and checked the fuses but I am getting nothing.

Any insight would be appreciated.

Thanks!

Battery cables ............

Ayup -- Power is not getting to the system. More likely the positive cable, since battery acid can ooze under the insulation and eat the cable up like termites will do to a 2x4 inside your wall -- unseen.

While it sounds basic, using a simple volt meter to test for the location or lack of it is generally a sound basic way of testing for a problem like this.
If you have never used one, it is understandable that it is intimidating.
Suggesting to throw parts with out having a clue as to what, where or why is expensive.
Harbor freight generally has their $9.00 digital volt meter on Sale for $2.00. It is almost as good as the $400.00 digital voltmeter I have, along with about 5 of the harbor freight models.
The battery cable I had to buy was for a Ford Focus, available only at the dealer and at a cost of $120.00.
And as it turned out, I could rebuild the one that was in the car with spare parts I had in the garage.
A voltmeter told me enough information to determine where I could spend the $120.00 for more fun. Faster horses, looser women and burbon.
