摘要:
When an ignition switch (22) is operated to other than a start position for cranking an engine (20), a switch (relay 28) places a megafuse (30) in circuit with protecting cables to the electric starter motor (18) and alternator (16) to protect against shorts. When ignition switch (22) is operated to start position for cranking the engine (20), switch (28) removes the megafuse (30) from protecting the cables. If a short blew the megafuse (30) before starting, the ignition switch (22) cannot operate the switch (28) and the engine cannot be cranked.
