Alright. The bulkhead is normal. The diagram is as if you were looking down at it.
I measued a consistent 11.5 volts from the N connector. As well as the three endings of the run circuits.
However, when i was measuring resistance at the ballast, the upper right terminal and lower right terminal both gave me about 3.4 ohms.
This is different from what you said. If i uderstand correctly, the upper right terminal should have 5 ohms, and the lower right terminal should have 0.5 ohms?
Does this mean wrong ballast?
