Starters can act pretty funny sometimes. When I start having problems, i usually just replace them so it does not leave me somewhere. Has the starter ever been changed? If not its probably about due. As for the wires, the positive cable that goes from the fender mounted solenoid goes to the starter(thick red one). Its hard to see the connection at the starter though unless you are under the car. Starter is on passenger side mounted between the engine block and transmission bell housing. Sometimes that starter wire touches a hot exhaust part and arcs when it touches the metal. In other words the rubber insulation of the cable burns thru to the metal, touches metal exhaust(a ground) and shorts out. But my guess would still be the starter going bad. I would not trust it if it allready gave you trouble. It probably will act up again.
