I have been trying to complete a calibration on this system sense we blew a HV cable and it arc to the frame of the unit. I replaced both HV cables and cpu board as well as the 1khz board, kv/filiment board,the charger board,and the rotor board. I get up to the taps calibration and can't seem to get any higher then 60 kv and it drops to 50's kv and keeps recycling. I can pass the taps test, and bypass the checksums and take the technique up to 110 kv/25 mas with no problems. I have had errors 329 and 469 through this process. Any help will be appreciated.

ERROR 469
During Calibration:
1. Check If K7 Contactor On AMX1A4 Panel Pulls In - Check For Welded Contacts
2. Check That No Wires Or Side Cover Insulation Interfere With K1 Thru K6
Contactors On AMX1A4 Panel
3. Check For Bad Crimp On Red Lead To AA Of Q3 On AMX1A4 Panel
4. Check For Defective Jumper Harness From J3 On 1 KHZ Board To J7 On
FIL/KVP Board
5. HV Cathode Cable May Be Shorted
6. FIL/KVP Board May Be Defective
7. 1 KHZ Board May Be Defective
8. Check Spark Gaps On HV Xformer For 0.010”
9. Check For Location Of Black & White Leads On Q3 Block On AMX1A4 Panel
10. Q3 Block May Be Defective
11. Check If EXP START CMND Is Shaky (This Is Like 439 During Applications).
EXP START And SCR HI/LO Are Single Pulses
12. “XRAY ON” Going Low = Bad Tap Relay Contact(s)
13. Bad Handswitch
14. Bad Rotor Board - Also Check Stator Lead(s) For Continuity
16. Bad XRT - (HI FIL LIMIT ERROR) With 439, 467, OR 469 Error Alone - Usually At
Higher KVP’s (KVP Waveform Will Be Low On The Front End, Even In Check-Sum
Bypass Mode)
17. Bad High Voltage Transformer
18. C5 Leaky Or Bad
19. 439 And 469 ERRORS – Check ALL Leads That Exit The AMX1A4T1
Autotransformer --- Look For Pinched Or Shorted Leads To Ground
20. Check Pin Spread On Both Ends Of Cathode Cable (Also Check For Proper Amount
Of Grease In High Voltage Cable Wells)
21. Refer To ERROR 439 - Item 2.
During Applications:
1. There May Be Oscillations Or Trash On The “XRAY ON” Signal
(Could Be Bad Tap Relay Contact(s)
2. Could Be An XRT Spit Or Bad XRT
3. Possible CPU Board Failure
4. Hand Switch Or Coil Cord Failure
5. Soft Batteries/Cells
6. Tap Relay Contact Bounce - Replace 1 KHZ Board
7. Side Cover Fish Paper Insulation Impacting Tap Relays When Cover Installed
8. Bad Handswitch
9. Bad Rotor Board
10. Check Stator Lead(s) Continuity
11. Refer Also To Faults “During Calibration” Above

Did you load test the batteries?
