Integration Wiring Confusion [resolved]

(1/6) > >>

DustDoggy:
So I completed my reduction last week and everything went great so today I thought I would install the integration upgrade. Installed the shunt regulator board and went to check the voltage but noticed the 4 LEDs didn't light up and one LED on each tube socket didn't light either so I turned it off. After checking over my work I noticed my Integration manual has the red wire that is to be disconnected from 4L connected to 57L. My red wire that was disconnected from 4L is attached to 56L. When checking back to my reduction manual it says that 56L is the correct position for it.
I'm not sure these two problems are related but before I go reflowing all the joints I thought I would post here first. Thanks!

Paul Birkeland:
56 and 57 are wired together, so there isn't technically an issue with this. 

In order to actually debug what's going on, you would need to perform the voltage checks on page 17 and let us know what is correct and what isn't correct.

If you have one LED on one of the 6922 sockets that isn't lighting up, but the other three are lighting up, then you almost certainly have an issue with the underlying build that needs to be addressed first.  I fix a LOT of Reductions with the repair service and I think I have maybe seen one with actual mistakes made, whereas the rest were just poor solder joints that didn't capture all of the connections on a given terminal.  This is extremely common on the ground buss wires that run from the input RCA jacks around the 9 pin sockets and into the terminal strips.  Pretty much every Reduction I have repaired has a loose wire on pin 9 of at least one of the 9 pin sockets, and this is definitely something that will cause one LED to not light up.

DustDoggy:
Thanks Paul! Some reflowing in the suggested areas seemed to do the trick. I just finished the final voltage check and terminal 2 seems a bit high at 101 VDC. All others are within the specified range. Anything to be concerned about?

Paul Birkeland:
Are both the LEDs glowing on the 9 pin socket on that side?

DustDoggy:
Yup they both are.
