Yet another SIP Speedo Question

So just purchased a SIP Speedo for my SX150 with electrical ignition, problem is it doesn't seem to work at all ?? My questions are,


1. Do you need the power box on an AC installation or is it just for DC bikes ?

2. Wired up through the Power Box i get no lights no nothing, will SIP take the unit back for repair ?

3. Or could it possibly be the Power Box that's faulty ?


Thanks in advance
