5.Remove lead #227 from terminal B1 on the control board. See Figure F. 34.

6.Remove lead # 262 from terminal B2 on the control board. See Figure F.34.

7.Remove lead #232 from terminal B3 on the control board. See Figure F.34.

8.Note lead placement and routing through insulation for reassembly.

9.Using the phillips head screw driver, remove the control board mounting screws. Note the location of the different types of screws for reassembly. The machine screws have lock washers and flat washers, and they mount the board to welded nuts. The sheet metal screws mount to the nylon standoffs.

10.Carefully remove the control board assembly. Note insulation placement for reassembly.

11.Using the phillips head screw driver, careful- ly remove the engine protection board and CV board (if used).

REASSEMBLY

12.Using the phillips head screw driver, careful- ly assemble the engine protection board and CV board (if used) to the new control board.

13.Carefully fit the control board assembly in place. Note insulation placement.

14.Using the phillips head screw driver, mount the control board with the appropriate mount- ing screws. The machine screws have lock washers and flat washers, and they mount the board to welded nuts. Make sure these are secure since they are used to ground the control board. The sheet metal screws mount to the nylon standoffs.

15.Attach the leads to the control board. Note lead placement and routing through insula- tion.

Lead #227 to terminal B1. See Figure F. 34.

Lead # 262 to terminal B2. See Figure F.34.

Lead #232 to terminal B3. See Figure F.34.

16.Carefully connect the molex type plugs to the control board, engine protection board and CV board (if used). See Figure F.33 and the Wiring Diagram.

17.Using the 5/16" nut driver, install the control board cover and the front control cover assembly.

18.Perform the following calibration procedure.
