i have had little experience with piezos but there is little to go wrong with them,  as yours came  prewired  the only thing i can think of is that yes, you have a serious earthing issue there or a short, the bridge should not need earthing...have you tried testing with another guitar lead, or tested the amp with another guitar, or tested on another amp?  If ok go back to the guitar, disassemble and you might find a reason for the fault, if all else fails you could ask Ben for a replacement...

Try running wire from your jack to your string or bridge

i,ve never had to earth to strings with a piezo,but it is a good place to start,other than that you might try reversing the polarity,by the pics that will be difficult at the disc,you,ll have to change it at jack

Yep, bad ground. Only places to look with that harness are the ground wire going from the vol pot to the jack, and the one going from the piezo to the vol pot. It's probable one or both of the solder joints is bad. Then there are the other alternatives: bad guitar lead cable, bad ground at the amp, bad ground at the wall socket. Once you get those sorted, then you could try running a ground from the metal bridge to the back, not the tab, on the vol pot. I doubt that's really necessary in this case, as the twisted pairs on the harness are cheap shielding, and the piezo works through vibration, not magnetic field.

Just like there are "Monday Morning" cars, I'm sure there are MM harnesses. Somebody hadn't had their coffee and missed a solder joint. Don't forget to clean the grounding point on the peizo before you re-solder it.
