I finished my battery relocation the other week and now all of a sudden my digital distribution block (Xscorpion DMANL3034P) is displaying a voltage of 0.00 V. I know this is incorrect as I have a digital display on my positive battery terminal which reads the correct voltage and everything is operating properly. Has anyone else encountered a problem like this?

Is it grounded correctly?
Photos of your setup?

Yes it is grounded correctly. The digital distro block is grounded to the frame and I have my two battery grounds (one to the trans and the other to the taillight ground, see pictures below). I have actually narrowed the problem down to my HIDs. When the headlights are off the digital distro block reads the correct voltage. However, when I turn the headlights on that is when the display will read 0.00 V. I originally had the HID harness +12 V attached to the under hood fuse box. I contacted Cullen at RSX Retrofits where I purchased my HIDs and he suggested running the + 12V from the digital distro block. As you can see from the pictures I have tried this as well and have ended up with the same results. To be honest I am out of ideas except to try another digital distribution block...

Side Note: My digital distribution block is wired as follows.

Input: 2 AWG Power Wire
Output 1: Starter (250 amp ANL)
Output 2: HIDs (60 amp ANL) Has a 25 amp in-line fuse
Output 3: Under Hood Fuse Box (100 Amp ANL)

Headlights Off:


Headlights On:


Trans Ground


Circuit Breaker (100 Amp)

You can make a cheap Faraday cage to go around your HID ballast, ground it, and see if the problem goes away. If you do it correctly and it doesn't solve the problem; I assume that the interference is traveling along the power wire (harmonic noise). In that case; you could try a cheap car stereo power line filter (protects stereos from alternator/coil interference). But it would need to be able to safely pass the amount of juice that your HID kit draws.

Thanks for the suggestion. I am very much a beginner when it comes to audio interfearence issues. The power line filter that you mentioned would that be something like a ferrite core noise suppressor?

Ferrite is a stone or mineral, I think. A Faraday cage is a metal enclosure that's grounded and keeps electro-magnetic signals from passing through it. Google it and you'll that it can be complicated or simple.

You could probably experiment with a small cardboard box lined with aluminum foil. The foil has to be touching metal directly or via grounding wire.
