find the conector and wire color and check the voltage with the regulator disconnected.

Briggs engines use a flywheel generator that produces AC - this is rectified to DC using either a single diode or the modern types use a proper rectifier and voltage regulator pack - identified by noticing cooling fins on it. Electric starters use 12v DC. Quote the 3 banks of number code digits to a B&S agent and they'll tell you what you need.
