Those are correct. I just pulled the cover off my (working) 1000 M-Series that has a later model supply (5061-6630 date code 2601) but has the same motherboard as yours (5061-1371). J1, J2, and J5 are as above -- Preregulator (5061-3457), Inverter (5061-3454), and Control (5061-6627). I have the power fail option, so J3 is the Battery Charge card (5061-1348) and J4 is the Battery Backup card (5061-1349).
Ok, thanks! I just tried mine again, it's a dud so I am going to have to figure it out. First step was to see if the rectifier had any voltage so I disconnected the + side and checked it with a voltmeter. With 120v plugged in I saw 200v DC which is probably not too far off. That seems to go to the inverter card, which I don't know what it's doing with that.
Is there a block schematic of what does what on this PS?
