so parts arrived.......i'm gonna install the AVR tonight Chris.........do all the connections on this new avr correspont to the old connections on the avr from top to bottom? meaning the old avr i numbered the wires from top to bottom 1-6 and i know that that order does not correspond to testing as i found out also once this is all plugged in i see a small set screw on the little blue thing upper left.........how do i adjust this/ to what spec? i assume i have a dvom hooked up and to what scale set? and where do i hook test leads to if it all works once hooked up?

Yes, all wires land in the same spots on either voltage regulator.

You'll need a decent quality meter. Voltage should be around 242-245V from line to line or exactly half from line to neutral.

A small flat head screwdriver will allow you to adjust it.

Well, after almost 2 years it is fixed!! new avr and avr all adjusted now and she has output 243-244 volts!!!! thanks a million to Chris for guiding me through the troubleshooting!!!.....I had been on another forum that gave possible problems which some were listed that were my problem but no good info on where to and how to start troubleshooting....no a very good forum in my opinion or at least a tech savy one, which caused me to dabble around for over a year and a half with no real conclusion....and furthermore it claimed to be a Generac service forum were no one tech savy enough could tell me specs and what and where to troubleshoot, just a list of possible ideas of what it "could be" I'm sure glad I found this forum!!! In about a weeks time Chris had me narrow the problem down through his expertise skills!! I will be back to this forum, as Chris is the man!! Read the thread and you'll see how well he knows his stuff!! and I bought the parts or at least my mom did from him as a token of our appreciation and we'll do it again if need be......well, we hope not to have issues in the near future..lol anyway, so the fix for this was dirty brushes and slip rings and a bad AVR!!! Thanks once again Chris!!!!!
