1) Check the voltage at the end of the AC adapter.
If it’s not 6-15VDC, get a new adapter and/or go to step 4.
2) Check the voltage at the terminals (on the tap) that connect to the VB pad.
If it’s not 6-15VDC, get a new tap and/or go to step 4.
3) With the pad’s switch on, check the voltage across pins 5 and 6 on this diagram:
If it’s not 6-15VDC, get a new pad and go to step 5.
4) If you can’t get a new adapter or tap, perform “trafo mod” and proceed to step 5.
5) VB ON!
Hope that helps…
PS: The VB also requires a certain amount of current to run. I’m not sure what the minimum is, but 800mA to 1A should be a safe bet, even with “other stuff” attached (e.g. possible future expansion devices, etc.)
