Tempest power brick voltage - am I reading this right?
My Tempest started acting up so I decided to check the voltages. After chasing my tail for a while and the problem getting worse the game stopped working. The +5 was reading 0.44.
I tried another known good AR II and it read the same.
So, I tried to check the power brick. I put the ground lead into pin 5 and checked the DC voltage for pins 1, 2, and 3.
I was getting about 0.88 which looks really wrong. I was expecting around 10. Here is the odd part though. While I was measuring it the voltage slowly started to rise. I watched it hit 2.2v before switching it off.
Anyone have an idea whats going on here or maybe I am reading it wrong? I am counting pin 1 as the bottom right and counting right to left. The jagged part of connector towards me.
