When you say "When certain parts are removed and it still sort of works, out it goes", I'm assuming you mean to the public. - I'll have to 'read up' on this guy, Muntz!
According to the specs. on the PS cover:
The output is: 15VDC @ 50A = 750W
The Max. output is: 800W
Can I assume the current limit has been factory set to 106.67% ?
And is that high enough to equalizing lead-acid batteries? - Thanks, Jack

Hi Jack
Isee you have the adjust pot set @ 13.6-13.8 Vdc which is the range for "floating" a fully charged 12V lead acid batt. this is great for keeping a battery in standby or storage. But, when you connect a discharged battery at 13.8V it will trickle charge at low currents, so it may take a day or two to charge up. so your not fully utilizing an 800W power supply! how much current can U use? depends on both the batteries size and / or parasitic loads. Most batteries have max charge current ratings! This is a very safe set it and forget it voltage if you don't care about being back up to full charge in a timely fashion.
"equalization" is done as periodic maintenance to maximize battery life , about once a month or so for an hour or two. This is done at high voltage and low currents on a fully charged battery. The equalization voltage and current depends on the batt. size and chemistries, see manufacturers guidelines ~ 15.0-16 Vdc. Equalization basically keeps the electrolytes stirred up with bubbling action and helps keep the Pb plates from sulfating (bad).
Bulk charging along with a resting charge are both done to minimize charge time for a full charge.
most "smart chargers" do the 3 phases but not equalization! so to get the most out of a battery it's still a manual task.
