1.Turn the engine OFF.

2.Perform the Alternator Rotor Removal procedure.

3.With the 1/2" wrench, remove the four nuts and bolts holding the case top and doors assembly to the welder frame. Carefully lift up and remove the top and doors assembly.

4.With the 3/8" nut driver, remove the two leads from the alternator brush holder assembly. Note lead placement. Set brush holder aside.

5.With the 1/2" wrench, remove the battery.

6.With the 3/8" wrench, remove the bottom alternator cover.

7.With the slot head screwdriver, remove the commutator wrap-around. See Figure F.14.

8.Disconnect the yellow and white wires at the in-line connectors. See the Wiring Diagram and Figure F.15.

9.Disconnect the two yellow leads. One is located at the field bridge and the other at the field fuse holder. Cut any necessary cable ties. See Figure F.15.

10.Remove the tape and using the 3/8" wrench and slot head screw driver, discon- nect the black auxiliary power lead from the current transformer. Cut any neces- sary cable ties. See the Wiring Diagram and Figure F.15.

11.Remove the red auxiliary power lead from the CB4 circuit breaker. See the Wiring Diagram.

12.Remove the white auxiliary power lead from the 115VAC receptacle. Cut any nec- essary cable ties.

NOTE: The CB1 circuit breaker may have to be removed to access the terminal for the white lead.

13.Remove the red lead from the negative ter- minal of the field rectifier bridge. See

Figure F.16.

14.Remove the black lead from the positive terminal of the field rectifier bridge. See

Figure F.16.
