9.Reinstall the brush holder assembly after the test. Depress the spring-loaded brushes into the holder and slip a suitable non-metallic, fair- ly stiff retainer through the slots at the top and bottom of the holder. A cable tie works well; see Figure F.3. This will hold the brushes up so that you can easily install the holder.

10.Slip the holder into position in the generator end bracket. Be careful not to loosen the 2 attached wires.

11.Reinstall and tighten the 2 screws with the 1/4” nut driver.

12.Slowly remove the non-metallic retainer from the brush holder and let the brushes snap back against the slip rings.

13.Snap the brush holder cover back into posi- tion.
