Exclamation Alternator not charging

Newbie here !

I use a 1999 F-550 with 7.3 powerstroke as my delivery truck. Been a very reliable truck. with the exception of the alternator (generator) now not charging. I have put 3 different (new) alternators on it with same results.

It has been at a mechanics shop for 4 days and he can't find the issue, but I fear what ever hours he has in will be billed to me, with no results.

As deliveries are my bread and butter, I am desperate to get my truck back on the road.

I know it could be a hundred different things, but can some of you help me start at step one and work from there?
Single alternator, dual batteries, (not the ambulance package).

Thank you in advance

DD
