I have a question hopefully someone can answer or explain.
I made a jumper for my two chassis Pass pre-amp, but haven't figured out how to hook it up. The chassis screws aren't 'normal' screws, but are like threaded rods, or inserts, with no 'top' to put the spade under. I am referring to the screws on the top and side. I haven't pulled the pre out yet to try the screws on the back as shown in the picture below.
Anyway, while doing this I measured the resistance between the two chassis (one is P/S, other is electronics), and there is no common ground between each chassis. It measured as an open.
So, if I were to ground this to the Triton would it make sense to ground both, or just one of the two? I can certainly experiment once I figure out how to attach the spade, but was wondering if anyone has any thoughts. I think I will send an email to Pass and ask why the two chassis are not grounded together. They connect via a DB-25 umbilical cable.
