| The Main Circuit Breaker is supposed to protect the wiring from a shorted battery. If the regulator is connected directly to the battery (as shown on the diagrams), not utilizing the main circuit breaker for protection, there is a potentially dangerous situation. If the regulator internally or externally shorts that wire, connected to the battery, to ground, the battery will supply upto 200 amps of current, **__causing the wire to overheat and possibly creating a fire__**. This is what the Main Circuit breaker is to prevent. | The Main Circuit Breaker is supposed to protect the wiring from a shorted battery.

The battery would be connected to the Main Circuit Breaker on the Brass Stud. | + | So, the proper way to connect the output of the voltage regulator to the system is at the output side of the Main Circuit Breaker (typically, on the Silver Stud).

| This is the way earlier & later model wiring diagrams show the connection of the voltage regulator to the circuit breakers. The L84-85 diagrams are the only ones showing this improper, potentially dangerous, wiring. | This is the way earlier & later model wiring diagrams show the connection of the voltage regulator to the circuit breakers.
