14. Connect lead 31 to unused “WHITE” terminal of
the 120-volt duplex receptacle. Connect lead 32 to
“CB 3” (circuit breaker 3) at the terminal that has
one black lead coming from the 120-volt duplex
receptacle. Connect lead “G” to the ground stud
located on the control panel. (Same location that
the 120-volt duplex receptacle ground lead is con-
nected.)
15. Peel backing from decals sent in mounting kit
package and install as shown in Figure 15.
Reinstall the two guards that were removed at
step 1. Be sure that the guards have a clearance
of at least one half inch from any electrically live
part. All new and existing leads must be routed so
they are clear of any sharp edges on the guards.
POLARITY OF THE STANDARD OUTPUT TERMINALS MUST BE AS
STATED IN STEP 15 AND THE MAXIMUM OPEN CIRCUIT VOLTAGE
WITH THE LOWER MODE SWITCH IN CV POSITION MUST BE AS
STATED IN STEP 16 BEFORE PLACING THE UPPER MODE SWITCH
IN CV POSITION. FAILURE TO HAVE THE CORRECT POLARITY AND
VOLTAGE BEFORE PLACING THE UPPER MODE SWITCH IN CV
POSITION WILL RESULT IN DAMAGE TO THE CV ADAPTER.

16. To check the VV output, place both CV/VV switch-
es on the CV Adapter in the “VV” position. Set the
Remote Control Switch to the “REMOTE” or
“LOCAL” position as applicable, if so equipped.
Start the engine welder and set for High Idle oper-
ation. Use a DC voltmeter to check the output
polarity. The “Electrode” output terminal that is
relabeled “Negative” must be negative and the “To
Work” output terminal that is relabeled “Positive”
must be positive. If polarity is not correct, recheck
Steps 3 to 12. Voltage should be about 40-60 volts
DC when the “Job Selector” control is set at mini-
mum and 90-100 volts DC when set at maximum.
These voltages may be higher if readings are
taken when welder is cold.
17. To check the CV output, place only the lower CV
Adapter switch in the CV position. Place the CV
Adapter Remote Control Switch in the “LOCAL”
Position.This may be done while the engine is run-
ning as long as no welding is being done. On
codes 10600 and above the “Job Selector”
must be at Maximum
. Check voltage between the
output stud on the CV adapter and frame ground.
The voltage should be less than 10 VDC. Voltage
between the “To Work” output terminal that is rela-
beled “Positive” and the CV Adapter output termi-
nal should be 7-12 volts DC when the CV Adapter
voltage control is at minimum setting and 36-48
volts DC at maximum setting.
18. If output varies greatly from that specified in Steps
15 and 16, check wiring and refer to the trou-
bleshooting section of the manual.
