S76's & Triple Tachs
Just when I thought I'd seen it all, another surprise.
Here's the deal:
Both Nr needles go to zero and stay there (on the ground by the way). Take a look around and note that both CB's are popped as well, ESS Bus and PRI bus.
What I don't know is how the Nr pickup on the MGB is wired inside. If the pickup is generating one signal only, and that signal is ultimately split between two independent electrical buses to their respective triple tachs, what might cause both CB's to pop?
Cheers
