Ok I am scratching my head on this and am going mad with this.
As some of you know I am trying to replace 4 Bochen PCB pots with standard manual pots. 2 circuit boards. Please see photo below.
I have tested the boards and they both work fine with the original pots. I use a solder wick and removed the PCB pots on BOTH Boards making careful note of the position of the pot, and numbers on a map of the board as well as the terminal holes 321 CW (they are reverse of a standard pot) I then soldered 22g wire (about 10" long) to the boards where the pots were . I then solder the other end to B series pots with the CORRECT value, connecting wire 1 to terminal 1 2 to terminal 2 and 3 to terminal 3.
Here is the problem When I connect it up, no output voltage is coming ( let me re-phrase the voltage matches the input voltage) I try to turn the Voltage pot up and down and nothing happens, on the LTC3780 buck boost the voltage does not drop or down, on the 1500w the voltage does not increase form the power in of 12v. It can go up to 85volts When I try adjusting the CC the same nothing, and the voltage cut out will not work either
I thought I might have burned out the board, but I thought I'd take a chance, I soldered in the original PCB pots and everything is working fine... WTH is going on???
Please help, I have wired everything in correctly of this I am sure, the #2 wire is the key, IF and this is a big IF (as I have quadrupled check the wires prior to powering up) I flip flopped 1 and 3 it would just change the atunation correct??
This is driving me crazy!!!! I don't get it please help me out...
