Hi Domenico and Dave, Thanks for the pics and the help . They helped a lot. The other question I have is that there is 3 componets on the power connector and one on the ground side of theboom screw. I cant tell what they are. I have two on the power connector and nothing on the ground pin. I know they need to be changed. Can you help with this?? Thanks Angelo

Hi Angelo,
In a separate email I have sent to you 3 enlarged pictures of the PCB for the KLM polarity switcher.
Please note that the holes from one side to the other side of the PCB are metallized.
When soldering the new relay do not use a too high temperature for the soldering iron otherwise the studs of relay becames oxidated (blue color)
If possible use solder from ALPHA METALS INC with 62 Sn, 36 PB and 2 Ag

I just took down my polarity switch for my 2 meter KLM and I need
to do
some work with it. I just receivedthe new relay to install but I
may have
damaged a trace or two. So anyone have pictures (without reply installed) or schematic of the board itself??? Thanks in advance.
