I recently installed a Rick's Rectifier/regulator combo on my bike and a 12V lithium battery (removed the old rectifier and regulator). When revving the engine the voltage at the battery terminals increases slightly. I am also noticing that all of the lights are dimming when revving the engine as well. I tested the stator and it is not grounding and seems to be within the manual's tolerances at each of the three terminals with the bike off. I am very new to this and would appreciate any help!
