It seems my off shift guys didn't understand what I needed them to collect. I will be trying to work on this during the day, it will be difficult to test in between trucks, but I think I can at least get some readings and see wtf is going on.
Shot in the dark here but where are you specifically measuring to? If measuring to ground, are you sure the ground for the transformer is bonded and this isn't a "floating neutral" situation?
Maint staff from third shift just stopped by my desk and told me they got the transformer working... I hate to think the blown fuse I found in the primary winding was the only issue.
Monkeys with hammers I tell ya.
