Hey I got a customer that came in this morning reporting his engine dieing while at freeway speeds...scary

I checked all the usual suspects like vacuum lines and battery ground from post to body. The customer reported no check engine lights when it happened nor any charging system failure.

I ran it for codes and there is nothing save a p2503 which there is no information on this code on Jaguar GTR. I have researched it further and found that the obdII code is charging system low output if im not mistaken.

I am not a tech but acting like one until my shop finds a worthy tech any advice here would be awesome.

Thanks,
Josiah

 

I have also tested voltage from the alternator to the positive cable on the battery post. I get 15.2 volts at the alternator and 15.0 at the post when the car first starts. i have checked fuse #82 in the passenger compartment actually i went ahead and tested all fuses in the area and everything checks out there.
