Hello folks.

I had to deal with a stalling 6.5 this afternoon. I had not much time to spend on it (sunday afternoon and family to care a bit ):h ) so I told the guy will see that during the week coming.

Here are the symptoms :

After the truck stall 200 kms away from home and the guy had it towed, I had a look.
Quickly I saw that the engine shut off solenoid wasn't clicking at wait to start cycle.
Found the 20 Amp fuse was blown.
Engine was cold, I replaced the fuse, she fired right away. I let her idle for minutes waiting anyhing to happen.
As nothing did happen, I went back home, telling the owner to buy a bunch of 20 Amp fuses just in case.

An hour after, he phones me, saying he is stuck on the side of the road, the truck blowing fuses almost quickly.
I took a new FSD with me, and go.
I mesure resistance in the harness with an Ohm meter searching for a short. Nothing. By the time I arrive, the truck has cooled down a bit.
I put on the new FSD, and she ran fine. I wait several minutes, still OK.

The guy was happy ans so was I. I went back home, half understood things fine, daugthers too, so no reproaches and we continued family afternoon.
That's evening now, and the guy just phoned me. He succeed in coming back to his home, after several fuse changes, and he says the truck is blowing fuse after fuse, almost immediately :shocked::wtf:

After a search on wiring diagram, I discover the FSD and PMD are sharing the pink wire protected by the 20 Amps fuse.6.5 electrical FSD power.jpg

So, I'm now enclined to think the FSD is fine, the culprit might be the extension or the PMD.
These were changed and relocated a year ago (D-Tech + extension)

Any thought? Any has already experienced that ?
It seems the problem is very critical when hot. PMD ?
