New here but not new to welding. Have an old Miller AEA 200LE (actually badged as an Air Products machine) Serial number HK253412. I'm working on it for a neighbor and was wondering if there was a better service type manual than the "Owners Manual" Something that actually lists voltages, control wiring and such.
This one has a few issues but nothing major. I just want it all to work when it goes back home.

So far I've gone through the fuel system, pulled the heads to clean up the valves and pistons and adjusted the valves, Runs like an Onan. Need to find a replacement plug for the stinger cable plug (got smashed by a horse!) General cleaning and adjusting the brushes, Then test it to be sure it all works.
May build the diode bridge and give it DC welding ability as well.

Thanks in advance
