OUTBACK® 185

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.

FIGURE E.3 - ENGINE STARTING, PROTECTION AND BATTERY CHARGING

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.

NOTE: Unshaded areas of Block Logic
