There probably was a short or overload if the battery fuse got blown.

After replacement of the battery and 80A battery fuse, does the headlights, interior lights (when opening doors), etc. work?

 

 

 

If you blew the main 80 amp battery fuse chances are there are a few other ones cooked too.
Check for voltage at the starter, the alternator, and the PCM.
Check all your fuses for continuity-replace any that went boom.
Check all your main grounds: Transmission to body, Engine to body, Battery main ground, as well as the grounds on the thermostat housing. Repair or replace any broken ones.
Then if you STILL have no power flow-start checking the grounds in the driver's and passenger's footwell areas.

If you've already done all these checks-let us know the results.

EDIT: Is the alarm factory or aftermarket? Is the vehicle stock? If no, list ALL aftermarket parts that tap into the electrical system.

 

If nothing works, then first check whether power is getting to the under-hood fuse box.

A multi-meter/voltmeter will provide better information than just a test light though.

At cable connection T1, measure if there is battery power at this connection. This is the battery cable connection that feed power to the under-hood fuse box. Standard battery voltage is 12 volts.




If there is battery power at Connection T1, individual test each under-hood fuse to see if there is power on both sides of the fuses that are more easily accessible.

Report your results. We'll try to progress along to narrow down where the cause may be. Cause may even be at the under-hood fuse box and/or wiring.

 

 

There is an open (break) in the power side (+). Part of this could be cause by a short in the power side (for example, power wire exposed and touching chassis ground or ground wire, two power wires touched, etc.)

Instead of initially checking at multiple power (+) and ground (-) points spread out all over the car, check in a systematic way. Start near the source (under-hood fuse box and battery), which is why I previously stated to check at the Connection T1 and under-hood fuses. The flow of power (+) and ground (-) starts at the battery. The flow of power (+) then goes through the under-hood fuse box to feed other circuits. One of the power feeds then goes through to the under-dash fuse box.

The car has many multiple circuits. To complete each of these circuits require of power (+) and ground (-). As there are so many separate grounds (-) for various separate circuit/components, the only way all these grounds would be affected at once would be if the battery negative cable and chassis ground in the engine compartment was bad.

Try checking systematically and follow the flow. Battery -> Underhood Fuse Box -> Underdash Fuse Box

 

Other than the battery negative cable to the main ground, no other individual ground connection would cause you to lose all power to everything.

 

Apparently I don't read very well, since there is literally no power to anything if I am now reading correctly absolutely nothing works this means:

1. There is no chime/interior lights on with key in ignition and driver door open
2. Neither headlights nor parking lights work
3. Radio/climate control fan/horn/power windows/power locks all don't work
4. Trunk light doesn't work

If that is actually the case do what Tech8 suggested and make sure you're checking for voltage not just poking with a test light. If we are understanding wrong and ANY electronic accessories work please let us know. By "checked main relay" describe EXACTLY what you did. Also if possible take pictures of the battery & underhood fuse box if you have a camera phone & upload them here.

 

Any update?

 

ok guys sorry for the late response. just got back from vacation. so a coworker did some trouble shooting. my starter was draining my battery. don't remember the exact words my coworker told me. but basically something about the grounding point of the positive cable that goes to the starter. I wish I could say exactly what he said. but we replaced my starter, charged up my battery and wala works. and ALSO the bumper to my brake pedal was broke so my brake lights was staying on even when the car was off. two things that kept draining my battery. smh im just glad my car is up and running now.
