Haha, oh man I hope that's not me. I have done some serious knuckle bashing on this thing for the last 8 years. I really hope I haven't done her in with such a stupid mistake.

The codes that I get are P0327, which was there before and P0560. The P0560 is low voltage.

 

It's very possible you didn't cook the computer. As LB suggested take both leads off the battery and get it on a charger.

Which car needed the jump, your LR or the other car? I hope it was yours because the computer could still/now be reading the P0560 code due to a weak battery.


Ok , odd question but what does the alternator smell like? Any cooked electrical/diode smell?

 

Let's hope so. It was my Land Rover that needed the jump. The car that provided the juice was my company car, it's 100% fine. I didn't notice a smell from the alternator but I'll check. The code is still there but the battery is at 11.67 just sitting in the truck.

 

I'd say it's time for a new battery.

 

I have had a battery show a good charge but be bad. I would pull it take it to the local auto parts store and have it tested.

 

I did this on my 3000gt VR4 and ended up melting a really big fuse, but nothing else, and yes it would not start with that melted, lots of people have probably done it, but its one you only do once

 

Battery is less than 1.5 Old. And won’t it still start with a bad battery that is being jumped from a strong one. I mean I could stay on the ingition forever, it turns over but never starts running.

 

Anything under 12v = needs replacing. If the vehicle is running 13.4v & up. Engine off 12.1 would be the lowest I'd trust as it really shouldn't drop below 12.5v with the engine off. 11.6 is on the low side if you ask me.

 

So no alternator stink then.

And IDK what fuses etc you have checked but just for giggles look at;

Engine Fuse Box: Remove Relay R9, look at/smell the contacts of the relay and box. Also check Relay R1. Give them both a lite thump with your finger in case a contact is stuck.
And Check Fuses F1=30amp, F10=30 amp, F12=20amp, F13=10amps And Check FL8=50amp

Passenger Fuse Box: Check F23, F24, F29 all 10amp, and F34=30amp.

And a longshot, pull a plug to see if they are fuel soaked.

The battery volts are low, but can you load test the battery where you are now?

 

I pulled the battery and had it tested, machine said it was good but needed a charge. Doing that now. I don’t want to get off track on the battery, if this thing had a bad battery and it is being jumped off it would still start. I checked all the fuses under the hood and under the steering wheel, everything looks good there.
