  • Publication number: 20110169445
    Abstract: The positive and negative pole of the DC-battery 2-1 is allowed to be connected to the solar panel 2-11 and the solar panel 2-14 when the key position of the ignition switch 2-15 is in a position of “on” or “acc”. The positive and negative pole of the DC-battery 2-1 is not connected to the solar panel 2-11 and the solar panel 2-14 when the key position of the ignition switch 2-15 is in the position of “lock” or “start”. To attain such a configuration, lead wire connects the ignition switch 2-15 utilizing relay 2-4-a and fuse box 2-4-b. When the position of the ignition key is in “on” or “acc”, positive poles of the solar panels 2-11 and the solar panel 2-14 are connected to the positive pole of the DC battery 2-1 via the relay 2-4-a. Relays 3-4, 3-15, 3-16, 4-4, 4-15, and 4-16 have similar function as the relay 2-4-a.
