Controller Circuit Board - Kohler 10CCOZ61 Service Manual

It is possible to check some controller circuit board
components (relays) without removing the component
from the board. These checks should be made prior to
installing a new board and attempting startup. Most of
the tests are referenced in Section 4. General
Troubleshooting. Use a high quality multimeter and
follow the manufacturer' s instructions. To obtain
