Bought a Tekpower TP3005T https://www.amazon.com/Tekpower-TP3005T-Variable-Linear-Supply/dp/B00ZBCLJSY
Trying to hookup the leads to find a short onboard using constant voltage/constant current mode. Runs a fan or lights that I hookup to it successfully but when I hook the negative to ground and the positive to ppbus g3h p.rail the power supply drops voltage from the 12.5v I preset it to 0.00v and blasts the max amperage I set which is 5.2amp once I attach it to the shorted rail. Do I need a better power supply, ie. agilent or am I missing something. Sorry for the noob question but I'm beating my head against the wall
