9. The negative generator brushholder, exposed
when bracket cover (see Figure 4) is removed, is
at the 11 o'clock position when the commutator is
viewed from the control panel end of welder.
Remove the 5/16 bolt which connects the two
existing cables to the negative brushholder. Obtain
the thermostat assembly marked "250" and recon-
nect the two cables to the negative brushholder
with one end of the thermostat assembly bolts
between the cable lugs and the brushholder.
10. Route the CV Adapter leads, which exit from the
bottom of the Adapter case, through a 1-1/4 X
3-1/2" rectangular opening located at the 5 o'clock
position on the generator frame. Inside the frame,
the leads should be formed against the frame
shell. Use the 5/16-18 x 5/8 bolt with hardware
supplied to connect the #2 heavy cable from the
CV Adapter to the free end of the thermostat
assembly from Step 9. The flat side of the cable lug
should be against the bottom side of the thermo-
stat assembly with the nut, washer and lockwash-
er on the top.
