Let's start slow. If you mean you have no power (no lights, no nothing) then you likely have the infamous ampmeter problem. Before I bypassed my ampmeter and installed a voltmeter, the wires on the back of the ampmeter (the primary wires) would come loose (the nuts would back off), the connection would be no good, and I would have "no power". Also, if your ampmeter has been "smoked" the same thing will happen. Is this the problem you are having?
