I am repowering a Craftsman mower that currently has a Dual Circuit alternator with an engine that has a regulated system. The B&S publication shows splicing in new system, which looks straight forward. However, I have read on-line that someone did a similar wiring configuration which caused groundfault issues. Does anyone know if grounding the output of a voltage regulator causes any issues. The wiring schematic for the mower shows that with the key in the "off" position that it does put this circuit to ground.
