All Elec. Pwr cut off when engaging starter
Hello everyone. I have a problem and I can’t find any similar blogs entries anywhere. Could use a hand.
BACKGROUND
- 2004 Disco w/ 66k miles
- Sat with dead battery for a few weeks and just dropped in a new Duralast Gold last night.
- Reads over 12V on multimeter.
- No rapid flashing alarm light, so I believe the immobilized is not active.
When I go to crank the vehicle, it behaves properly until I engage the starter. At that point, all electrical power to the vehicle is shut off. If I disconnect and reconnect the battery, power is restored, but the cycle repeats when I try to start it again.
I am seeing a “permanent voltage supply”
code as well. Resetting and trying to start again yields the same result.
I appreciate any assistance! Andy

Thanks for the response.
I don’t drive it that much (hence only 66k miles), but I do keep a battery tender on it because she does like to be at 100% (else the codes start coming). Anyways… I think the battery just gave out, but now I’m wondering if it isn’t a fuse or something like that. Checking that next.
Also, I just took the new battery back to autozone and it checked out on their tester.

There is no better friend to a battery than a wire brush, widely available like----> https://www.povezisej.com/index.php?...ucts_id=912676
Immersing terminals and connectors in hot baking soda solution cleans a lot the incrustations.
All terminals in cables must be shiny clean and tight.

Solved
Well, folks… That was the problem. It took me a while to get to it, but with the new battery and a quick wire brushing of the terminals, she fired up like a champ. Took her for a spin and all was well. Even the three amigos went away! Although, I’m certain they will return. Lol.
Thanks again for the help… Andy
