Putting WG4700 Series monitor in R-Type

On Sunday night I got the bug to progress with this.

I had to take a whole bunch of stuff apart in the hacked together Mr. Do! cab, so much so that I am not completely sure I could get it back together again after another month or so. I would more than likely probably forget.

I got the monitor out and the isolation transformer. I brought everything out by the R-Type, and took the nice monitor out of the R-Type. I gathered up my supplies and remembered that I didn’t have any solder wick. I was going to need to add longer wires to the Isolation Transformer and I would have to desolder the old wires. I wanted to have a new clean connection, so I would just wait until I got more wick.

On Monday I got some wick and immediately I went ahead and desoldered the old wires and cut new wires. I soldered them on, and then got to looking a little closer. I think the wire I have is probably 20 gauge, and there is a slight enough difference between these and the old wires in size that makes me think the old wires were 18 gauge.

So, I stalled again. Such a stupid simple question, but not something I know. What is the minimum wire gauge you have to use when connecting wires to the 0V and 115V connections on the isolation transformer.

I posted on the original topic I had made in the KLOV forums, and I got little reply in a day. Someone told me that it was bad to go down in gauge, completely not answering my question. I am not sure of the gauge, and not sure how to test it save putting it in the little holes in my stripping tool to see what is closest. That doesn’t seem exact.

So, back to bugging poor old Bob Roberts since he is familiar with this topic already.

He told me that 20 gauge would work, but 18 is better. So, I am going to waste what I did and put some 18 gauge on there, hopefully tonight.

The other issue with the monitor is the RGB connection. It was something pretty weird on the other game, the molex connector having wires going in every other slot, not right next to each other like you typically see with a RGB pigtail. I will have that stupid little hurdle to overcome.
