Just received my FREE Duo 250 from BMOW and he said last time he used it, it worked fine.

I grabbed a tested Duo charger off eBay, but I cannot for the life of me get it to turn on. Will it not function without a working battery? I am running it battery-less.

When I plug in the charger I get +24v give or take at the + and - battery charging pins. Over the course of the next minute or two, the voltage will slowly drop to 0v. 

PRAM is disconnected and I tried disconnecting the SCSI in case that was causing it not to boot. 

Any suggestions? The caps I can see so far looked good, and BMOW had it running about a year ago when he was testing his home built battery re-cell.
