Reading 0v on -V (-16v indicator blinking on lunchbox)
Hello, just completed assembly guide phase of the cp4500 and moved to setup. After plugging in pcb A with an extender into my 500 series rack and powering up im noticing voltage on +16 but nothing on -16. On top of this the -16v indicator light on my lunchbox is blinking (bento 6S). The only thing that didnt go according to plan 100% on my build, is the 2x10 male connector on PCB A. I thought i saw solder connecting two pins, however i believe now this is where the surface material of the pcb had come off. The light on the meter is not coming on aswell.

The 4 pins 7, 8, 9, 10 are all connected together to the ground. This is normal.
The V- issue is somethin different.
Do you have the same issue if the meter is disconnected?

Problem resolved! Was simply a solder point that was touching another on a capacitor. Silly me over looked it. Working like a charm now! Thanks for the response.
