ENGINE STARTING, PROTECTION AND BATTERY CHARGING (contin- ued)

BATTERY CHARGING

The Kohler engine has a built-in battery charging sys- tem. Output from the charging system is applied to the PC board where it is stabilized by the battery and then used to power the board electronics, the generator flashing system, and the hour meter. The remaining output exits the PC board, is routed through a fuse located inside the control box, and applied to the bat- tery.

NOTE: The engine charging system must be function- al for the Outback® 185 to produce weld or auxiliary output.

NOTE: The battery must remain connected at all times. If the battery is disconnected while the machine is run- ning, unstable voltage from the charging system will likely cause the PC board electronics to malfunction and may cause permanent damage to the PC board.
