1996 Sportsman 500 electrical problem

After installing a winch there was no electrical power to the switch or headlamps. During assembly I disconnected the 5 wires to the suspected regulator attached to the front grill. All wires were matched up on reassembly but not power. The battery is good since it powers the winch directly from the battery. Is there a reset switch that I must reset after disconnecting the battery or wires to the voltage regulator?
