Then it is safe to leave it as is. These systems work fine for most setups. But a Briggs 790292 regulator can be installed but that will cost at least $50 more. The yellow wire (voltage regulator) connects to the diode (Black wire) and red wire connects to the battery side. The Yellow wire from the Stator is for lighting and is an AC circuit. On the regulator diagram below would be the black wire (ei jumper wire). Connector would have to be removed and the regulator hard wired in place. Also the regulator case would need to be ground to the engine by either bolting it on or by a separator jumper wire.
