39. If you used method #2 to replace the circuit, push the slip ring assembly back into its proper position on the yaw shaft
while keeping the brushes depressed in their slots behind the assembly. A small pick can assist with this. Make sure
the plastic insulating tube remains in the center of the slip ring assembly and that none of the wires get pinched
between the slip rings – failure to do so may result in a short and malfunction. Replace the bolt with washers back into
the top of the slip ring assembly making sure the fiberglass spacer is in contact with the top slip ring. Tighten bolt to
approximately 75-80 in-lbs. See Fig. 12

40. Rotate the yaw shaft. Take a close look at each of the brushes to make sure they are properly contacting the
appropriate slip ring. Make sure each spring is properly seated in the rectifier slot and that the brush wires are not
being pinched. There will be fresh “brush tracks” on the slip rings. See Fig. 13. Also, make sure the slip rings are
vertically aligned.
41. If you used method #1 to replace the circuit, use the snap ring pliers to place the snap ring into the groove on the yaw
shaft. Make certain the yaw shaft is fully seated in the yaw bearing and the ext ernal snap ring is fully seated in its
groove.
42. Check the magnets on the rotor in the new alternator assembly to make sure there is no metal stuck to the magnets.
Any metal debris inside the turbine could cause the turbine to short-circuit and malfunction.
43. Orient the body as described in step 30. Using the three, small socket-head screws, connect the wires from the new
alternator assembly in the following order from left to right on the circuit board: #2 – Left Terminal, #3 – Center
Terminal, #1 – Right Terminal. Divert wires #3 & #1 around the PIC Chip. Do Not run the wires over the PIC Chip, this
can cause malfunction. See Fig. 13 below for clarity. It is important that the three ring terminals are parallel and
cannot contact one another once tightened. Torque spec for these bolts is 10 in-lbs.
