Did you try to jump it? Sometimes new batteries are bad too.

Could it be the starter or ignition switch?

 

Welcome! Hope to hear you figure it out.

 

Test battery, new batteries can be bad.

check all battery connections at battery

check grounds

Follow cables down from battery and check condition, check all starter connections, could be loose and there may be a fusible link somewhere in that run that is bad

 

Sounds to me like something is grounding out when the ignition circuit is made. Welcome from LA (Lower Alabama)!

Did you ever find and fox the issue? Just got the same thing yesterday. Battery was super corroded. Got a new one, turn the ignition and I lose all power. No fuse are tripping, but I’m getting a voltage of 2V between the negative terminal of the battery and the chassis. Disconnect, reconnect the battery, start fresh, same thing.

 

Hi all...new to the forum. Came to reply here asking (hoping) someone came up with the answer to this. I have the exact same issue...just as described above. Turn the key, power goes out. Pull the battery, wait a tick, reconnect. Power back on. Turn the key...stone cold dead.

Thanks all...

Edit: check this thread....seems like someone found an answer for their same problem

Did you try the fix in that thread? I’m having g the same issues but it’s super random. Sometimes it starts fine and others it shuts the electronics off. I plan on checking all connections and alternator with multimeter and reporting back
