Is there anyone out there who has or knows someone with a used HV tank (46-270954G1 T3432AP) or the Rectifier pcb for the HV tank (46-184899G2)
Error codes 439 and 43B on exposures. Only 35MA coming from tank on exposures.
1. Recalibrate The Generator Only If The Exposure Time Is Longer Than 2 Msec And The KVP Is Less Than Or Equal To 75% Of Selected KVP
2. Check That K7 Contactor On AMX1A4 Panel Closes (Contacts Welded/Loose Leads/Bad Coil)/Verify Proper Micro switch (Aux) Closure (Contactor Kit 46-262695P5). A Faulty K7
Might Not Give Any Errors—But You Will Not Be Able To CAL THE CHARGER In The Calibration Mode. As A Rule, If The Unit Was Manufactured Prior To 6-94, REPLACE The Contactor Assembly
(46-262695P5)
3. FIL/KVP Board May Be Defective
4. 1 KHZ Board May Be Defective
5. Loose Connectors On FIL/KVP Or 1KHZ Board
6. Stop/Start SCR Q3 On AMX1A4 Panel May Be Defective
7. If EXP START Is Shaky Or Hi All The Time (It Should Be A Pulse),Troubleshoot The EXP START CMND Circuit On The 1 KHZ Board
8. Verify That The Tap Relays Contacts Are Coming In Firmly - No External Interference
(Fish-paper Loose/Curled On Inside Side Cover?)
9. Loose Leads On Service Toggle Switch (Not Going To Applications)
10. Bad CPU Board
11. Bad Rotor Board
12. Bad High Voltage Transformer
13. Loose Anode OR Cathode High Voltage Cable-Spread Pins At Both Ends Of Cathode HV Cable
14. P1/P2 Leads Exhibit Leakage To Ground
15. 439 And 462 Errors Together Indicate Battery/Cell Problems
16. 439 And 43E Errors - Replace FIL/KVP And 1KHZ Boards Check Fil. H/V Cable
17. AMX1A4C5 Leaky To Ground
18. Refer To Item 19. -- 469 ERROR Listing
19. AMX1A4C6 Bad (FIL/KVP Bd. J8 Pins 1 & 2)
20. Soft Batteries/Cells
21. Bad Main SCR(s) Q1 Or Q2
22. Bad AMX1A4R7 (Auto-Transformer)
23. Bad Tap Relay(s) – Check The K6 Tap Relay For Good Normally Closed Contacts
