Carl,
Thanks!
He would ko see that proble goin between different power blocks with a engine. This would put a short on the transformer tripping over current red light...then possibly tripping the breaker. It sounds like it also worked before. He never stated if he has tried it without a command base powered!
Just to clarify, there aren't any crossovers, only two independent loops. I never saw the traditional ZW trip lamp light except during the reset.
