The adapter boards have a small pad (or loop) marked "test" on them. Check that the voltage is the same on the test point for each board, and there is good continuity between them.

Voltage looks right, but where did you attach the clip to get the voltage? I've seen a few instances where people try the 5v test points on the CPU or lamp driver boards, and unfortunately those do not work. Also, it does need to be connected to a controlled lamp power line, and not a GI lamp circuit.

Quoted from Fytr:

To get the voltage readings I put the positive lead on the test points on each of the adapter boards and the negative on the braided ground wire in the head.

For the voltage readings, yes. I was referring to where you attach the alligator clip on the LED adapters.

R8f1k;

Are you still seeing the LED's slightly-dim at all times, with around 7.5v on the LED adapter test points?
