Will do SE. Merci bien!
Now that I've thoroughly inspected the interior wiring of my Northern 564, I'm a little disappointed in the craftsmanship
All the lamp grounds run back to the lamp ground for line one, that's why there are shorts on the amp connector leading from pin 3/28 tip to the rest of the lamp grounds.
That's a little cheap in my opinion. So it's a good thing that I ordered the cable, because now I can give each lamp the grounding they deserve!
