Bad connection, ignition key, kill switch, engine connector

sounds like a bad connection somewhere.

Decided to replace my starter, as it was looking rough anyway. Question though, ill upload a pic later but I have 2 black wires and 2 red wires connected to the same post on the solenoid.Seems odd, but has worked the last 4 years since the shop installed my last starter.

The manufacture would not use black for any power connections, assume prior owner installed something. Trace the wires
