The smaller posts are ONLY intended for minimal loads, virtually zero amperage. The purpose of the small lugs is to connect to the alternator's field sense circuit, which is nothing but what is self-describes: a circuit for the alternator to know what the system voltage is so it can adjust output voltage accordingly. The field sense circuit does not draw any significant amperage (if any).

So if you're running loads through this smaller circuit, I suspect you're overloading its capabilities and shorting or breaking the circuit.
