The capacitor bypass block is not labeled at least not in any documentation that I can find.

It has 8 capacitors inside and has10 wires and 3 terminals.

I'm hoping someone can help me determine which wire/terminal belongs to which capacitor. I want to replace all of them. I have toyed with idea of taking the block out opening it up to see if each one is labled inside.

I'm attaching photos and a sketch I made showing where the wires/terminal go.

Any help/advice would be greatly appreciated.

Jim
