Important: For Kohler EFI units: Unplug the harness from the ECU before performing any welding on the equipment.

CAUTION

Connecting the jumper cables incorrectly (wrong polarity) can immediately damage the electrical and/or EFI system.

Be certain of battery terminal polarity and jumper cable polarity when hooking up batteries.
