I have an arrow 500, 97 model. I'm having power supply problems in the CPU. Previously I have had to have 3 boards repaired and then the power supply went out. It had been replaced with an Athens power supply. I replaced it with the same thing and the machine works except for the computer just shuts down when in use. I have been directed by Dave at Siemens to purchase their power supply. Does anyone have experience with using one other than Seimens? Also, does anyone run one of these machines off of a phase converter? I am using a phase converter and I am wondering if this could possibly be causing the issues. Since putting in the new power supply I started running the CPU on a 115 vac to eliminate the possibility of my incoming electric causing this problem. Any suggestions would be appreciated.
