I think you're looking too deep, the problem must be simpler. Like fixing a car, 99% of the time it's simple, just go back to basics.

Put a 12 volt light bulb across the Jaguar inputs, you'll (literally) see any brownout or breaker issues as you drive.

You say the wiring is good, how do you know? Explain your tests and their results.

In all your posts I see a lot of assumptions and third-hand information. To really solve this, we need first-hand data.

Thanks.
