Morning! So its under the seat. I have new battery, new cables, and did the splices in the footwell. HOWEVER, something new today...

I had the Cayenne on a charger all night (at the posts in the engine bay). This morning I went to the garage and there was a CLICK sound. It was the 404 relay in the engine bay fuse box for the fuel pump.

ALSO, when I tested the voltage (at the posts in engine bay), it was only 2.5v. And so I tested it at the battery itself, and it was also 2.5. I took the battery out and put it on my bench, and tested it one more time, and it was around 10v...!?! I've had the charger on it for maybe 2 hours and its 100% charged.

I just found where the positive cable runs from battery to engine bay and its all clean and tight with good continuity.

So, even more confused today...!

Thanks for the insight though. Appreciate any extra set of eyes on this problem.

p.s. I do have durametric setup, but its not shown anything out of the ordinary...
