Hello and welcome!

My name isCustomerand I can assist you with your question.

Expert:  AMEDEE replied 5 months ago.

Are you looking for possible causes or would you like me to walk you through this diagnoses?

Customer: replied 5 months ago.
Possible causes would be neice
Expert:  AMEDEE replied 5 months ago.

It sounds to me like you just have a bad battery or a bad connection at or after the battery. What is the battery voltage at?

Customer: replied 5 months ago.
No It is like someone through a switch and turned everything off. The battery is fine less than a month old.
Expert:  AMEDEE replied 5 months ago.

Ok, good! So what is the voltage at?

Customer: replied 5 months ago.
a low voltage battery would not turn off everything!
Expert:  AMEDEE replied 5 months ago.

A bad battery would. So would a bad connection. Just humor me. Check the voltage.

Customer: replied 5 months ago.
Can't right now I am at work won't be home until 6:00 pm. When I turned the ignition this morning all lights came on. it was only when I engaged the starter that everything went out.
Expert:  AMEDEE replied 5 months ago.

Right. Thats because there is load on the electrical system. If there is a weak point in the circuit, thats when it will show up

Expert:  AMEDEE replied 5 months ago.

If the battery is new, you could bet it replaced for free under warranty. If it checks out good, maybe the connectiona t the battery are night tight enough.

Customer: replied 5 months ago.
when I get home what can I look for?
Expert:  AMEDEE replied 5 months ago.

If I am wrong, then we check power going to the junction block under the hood WHEN this happens. The battery needs to maintain above 10 volts when the key is in the CRANK position. Same thing with the voltage on the fuses under the hood.

Expert:  AMEDEE replied 5 months ago.

I can even send you a wiring diagram of the power distribution circuit to help trace down this power supply problem.

Customer: replied 5 months ago.
Nothing happens like I said it is like someone through a switch
Expert:  AMEDEE replied 5 months ago.

I understand.

Customer: replied 5 months ago.
I have fgot a wiring diagram
Customer: replied 5 months ago.
Is There a main fuse?
Expert:  AMEDEE replied 5 months ago.

Ok. YES, there are a few under the hood. We would need to check those as well after verifying the battery and connections are good.

Customer: replied 5 months ago.
I have looked at the fuses under the hood in the box as well as the ones on the driver's side access panel but I don't recall any that shut everything down.
Expert:  AMEDEE replied 5 months ago.

If the main or maxi fuse blows, there would not be any power at all. From what your descibing, thats not the case.

Customer: replied 5 months ago.
OK now we are getting some where. Where is that located?
Customer: replied 5 months ago.
I must not have explained it well because that's exactly what is happening!
Expert:  AMEDEE replied 5 months ago.

Either right off the battery or in the main fuse block under the hood.

Customer: replied 5 months ago.
Like I said, where is it located under the hood?
Expert:  AMEDEE replied 5 months ago.

I would need your VIN to give you the exact location

Customer: replied 5 months ago.
Would it be located in-line from the battery or labeled on the main fuse block on the other side?
Customer: replied 5 months ago.
Thanks I'll Check it out when I get home!
Expert:  AMEDEE replied 5 months ago.

You bet! I will be looking forward to your reply!

Expert:  AMEDEE replied 5 months ago.
