vax 6000 power supply schematics?

[hugl <huglhuglhugl%gmx.net@localhost>]

Hello,

nice to see the activity on this list :-) My vaxen (vaxes?) have  
spent a while asleep in storage, now I think it's time to power them  
up again.
I converted the vax 6610 from three phase to single phase around ten  
years ago, it worked fine on single phase power. Now I plugged it in,  
turned the key and after a short audible pop nothing happened.  
Turning the key just results in a relay clicking, no fans, nothing,  
so I assume I must be something in the very beginning of the power  
distribution that made the pop noise.
When I did the 3p-1p conversion, all I had were some descriptions, I  
did some sanity checks and rewired the box. Now I would like to have  
some schematics or at least block diagrams since there are quite a  
few enclosures inside the vax itself and I don't have a clue what  
they should be doing.
There's nothing on bitsavers, does someone here have documentation  
for the vax6000 series? Or a pointer to some information?

Regards,
Lo
