Hi guys... I have an XPR 4550 that a friend of mine purchased on Ebay and it appears to have no power out. I offered to take a look at it for him, but unless I'm missing it, I do not see alignment instructions in either the basic or detailed service manuals?

I will also look in the help files in the Tuner application, but I would have expected it to be in one of the service manuals. Anyone run into this?
