Hi there. Can anyone help me with this problem

I have connected my Whammy, Boss Flanger, Pro Octavia and Tremolo pedal into the Trex Fuel tank. My concern is this. When i only have 1 voodoo lab pedal I am able to power all my pedals with the fuel tank however when i connect another voodoo lab pedal eg pro octavia the fuel tank cuts out. now i know i'm not using all my mamps cause i connected a boss slicer and a trex replica into the fuel tank with my flanger and whammy and that works great. so my question is why would the fuel tank cut out on 2 voodoo lab pedals. and the answer is yes I am connecting it into the 9v output of the fuel tank :mrgreen:

The Proctavia uses a positive ground circuit design and cannot be powered with a common ground power supply together with negative grounded pedals. The 9v outputs of the Fuel Tank are commonly grounded. You will need to power the Proctavia from a separate power supply or one with isolated outputs.
