Low +5V in a BA23

[leegleason]

I have a MicroVAX i in a BA23 that interminttently hangs, halts, or machine checks, with a variety of messages. I've changed all the cards, no change. I noticed that the +5V in it is only 4.25 volts. Is that low enough to cause problems? And if so, is the power supply voltage adjustable?

I would think so. That's 15% below normal. I do not know if it's adjustable though.

Yes. Minimum voltage should be 4.75 Volts.
