So I bought this power supply (bk 1735a) a week ago, used but virtually not a scratch on it! Well I get home and plug it in and the digital panel ammeter is showing like 1.5a and the CC LeD is on and the volt meter showed 00.00, i could adjust the amps from .090 to 3.6amps but the voltage woulnt adjust for anything so, I started messing around with it looking it up etc and after about 5 hours I realised something really was wrong and It wasn't just me operating it incorrectly, so I opened it up and cleaned it all up and looked around for anything noticeable and I couldn't see anything so far, I used my meter in continuity thinking maybe the output is shorted and it's trying to set to set to hehe current limit which is why I can't do anything with voltage answer sure enough the positive and negative post were a dead short, so I followed the wires from the output to connector P5a (you will see on schematic) and unplugged te connector and to hehe be short on the output was gone so now I have tried to find the short on the big main board starting from that connector obviously but input am so stuck and confused and not even sure if it's supposed to be this way and imy wrong.. but after a day of searching the Internet every image o
n every site and place I could possibly find and not finding even close to the schematic for the 1735a I emailed bk precision and asked for it thought why not try lol an about 5 minitues after to my surprise they responded back with the full schematic and component values etc but even with this I am still lost.. sorry for my bad typing I'm using my phone and can't hardly see it! Thanks s so much for the feedback guys anything any help at all would be appreciated so much! I'm going to attach pictures of the stuff! Thanks ks again!!
