9.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 8. 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.

10.Connect leads 608 and 609, routed into the gener- ator in Step 9, to the two thermostat terminals.

11.Disconnect the white and yellow leads connected to the alternator brushes and reconnect the brush leads as before. Re-route these white and yellow leads over the top of the generator brushholder to meet the W and Y leads of the CV Adapter from Step 9. Connect W lead to white lead and Y lead to yellow lead using #10 x 1/4 screw and nut provid- ed. Insulate each connection with tape. Insure that all leads are well clear of moving parts and secured in place with tape.

12.Replace the roof assembly and bracket cover removed in Step 1.

14.To check the CV output, place only the lower switch in the “CV” position. This may be done while the engine is running as long as no welding is being done. Voltage between the positive output terminal and the CV output terminal should be 7-12 volts DC when the CV Adapter voltage control is at minimum setting and 36-48 volts DC at maximum setting.

15.If output varies greatly from that specified in Steps 13 and 14, check wiring and refer to troubleshoot- ing section of manual.

K385-1 MODEL CV ADAPTER

The K385 has been replaced with the K385-1. The only difference between them is the mounting bracket. The K385 was used on SAE-300 and SAE-400 Amp Engine Welder with AC Auxiliary power between codes 8813 and 9782. The K385-1 has a universal mounting brack- et which permits it to be mounted on codes between 8813 and 9782, as well as all codes above 9782 including the SAE-400 WELD’N AIR.

The Figures A and B show the mounting bracket in dif- ferent positions, depending on the type of fuel tank rail being used.

CAUTION

POLARITY OF THE STANDARD OUTPUT TERMI- NALS MUST BE AS STATED IN STEP 13 AND THE MAXIMUM OPEN CIRCUIT VOLTAGE WITH THE LOWER MODE SWITCH IN CV POSITION MUST BE AS STATED IN STEP 14 BEFORE PLACING THE UPPER MODE SWITCH IN CV POSITION. FAILURE

TO HAVE THE CORRECT POLARITY AND VOLT- AGE BEFORE PLACING THE UPPER MODE SWITCH IN CV POSITION WILL RESULT IN DAM- AGE TO THE CV ADAPTER.

13.To check the VV output, place both CV/VV switch- es on the CV Adapter in the “VV” position. If welder has remote control, set remote control switch to local position. Start the Classic II and place idler control in “high” position. Use a DC voltmeter across the standard output terminals to check the output polarity. If it is incorrect, recheck Steps 3 through 11. Voltage should be about 47-60 volts DC when the Fine Current Adjustment is set at minimum and 87-100 volts DC when set at maxi- mum. These voltages may be slightly high if read- ings are taken when welder is cold.
