while testing my capacitor bank with my psu i noticed a few problems and i don't know if it can be fixed, or if i need to just shell out the +$100 for a new one. its an old bk precision 1630. i was testing one of the capacitors by setting it at 2v 1amp and logging the time it took to charge and working backwards to see the real world capacity. it took shorter than expected and it ended up being 2100f instead of the labeled 2600f. but one thing i noticed is that it stopped charging at 1.84v when it was set to 2v. i hooked up my multimeter and put a 10w 1ohm resistor and the resistor got warm and the voltage didn't flinch. appears to be working so i shrugged it off and hooked up the next capacitor. thats when i noticed the amp meter on the supply was jumping off the scale! it was in current supply mode and set to 1amp so i don't understand how that could happen. i took the case off and i didn't see any loose solder joints or blown components.
