There are some things that might help that I didn't mention. Initially, I was having a shorting problem caused by a bad IC on the RS232 board. It was causing the power to cycle on and off. As I was trying to find that problem though, the SCR, which is Q6 started releasing its magic smoke. I replaced that, and while I had the board out, I noticed that many of the pins on the output header had cold solder joints, so I reflowed them. When I plugged the board back in, it wouldn't power up. It was this point where I found that the 30V zener had blown. When I replaced it, I got no power still, but I had given power to the board without a load on it, and found that the zener had blown again. I replaced it the second time with a 1 watt zener, and it was then that I got double voltage on all the rails. That is the 5V, +12V, and -12V rails. I got 10V on the 5V rail, and +24V and -24V on their respective 12V rails. I thought maybe something by the crowbar circuit had blown, since I was assuming that I shouldn't get more than 5 volts if that circuit worked. All the components tested out okay, although I only checked the 5.6V zener to see that it was still acting like a diode, but not that it was working at 5.6V.
Last night, I was looking through my zener collection, and I came across some 1 watt 5.6V zeners, and replaced the zener in the crowbar circuit, just because it seemed like a possibility to be the problem, but I have not tested the board since. In my mind, that wasn't what would regulate the voltage, but simply open up the SCR, and wouldn't be my problem, but it may be why I could see 10V on the +5V rail.
I put in an order for a bunch of capacitors I am getting short on last night, and decided to order a handful of optocouplers, although I haven't tried testing the one on the board, so that will be in the mail in the next few days. I'm going to get hold of Arrow right now and see if they can't add some TL431s to the order before it ships.
Anyway, you are now up to speed, and I think you could be right about the voltage regulator. I didn't look on that side of the board for the problem, since I was getting too high of voltage on the primary side of the transformer. I will test it when I get time later today.
Thank you for all your time helping me. I really appreciate it.
