charging issue

so i got the gauges to move but now the go to far right. i have 11 volts at the secondary terminal at each gauge but it flashes so this i assume is what the VR does so the voltage fluctuates down to 5 volts. this also tells me VR is working i actually install an external VR and it does the same as the one in the fuel gauge. question now is why do my gauges go all the way to the left when key is turned on
