PROCEDURE - RECTIFIER BRIDGE REMOVAL AND REPLACEMENT

1.To remove the rectifier bridge, first you will have to remove the field capacitor. Follow Steps 1 - 10 above.

2.Depress the retainer clip on the molded plastic holder and slide the rectifier bridge out.

3.With the needle nose pliers, gently remove the 6 wires from the rectifier bridge.

4.Replace the wires to their appropriate loca- tions on the new rectifier bridge (See the Wiring Diagram.):

Lead 200 and 200A are piggybacked on the positive (+) terminal. Depending on the bridge used, this corner may be beveled and/or marked with a + sign.

Lead 201 and 201A are piggybacked on the negative (-) terminal, which will always be located diagonally across from the pos- itive (+) terminal.

The two leads #7 and #9 are the AC side of the bridge and attach to the other two cor- ners. Either lead can go on either terminal.

5.Slide the bridge back into the molded plas- tic holder until the retainer clip snaps it securely in place. Snap the capacitor back into the holder and then slide the unit back into position in the panel.

6.Check that the leads are not grounded and for clearance and tightness.

7.Reinstall the case side, fuel cap, lift bail gas- ket, and case top.
