+-^CrossBow^- Posted February 2, 2023 Share Posted February 2, 2023 So you are reading 12v on the RCA jack on the switch box that the RF cable plugs into? Quote Link to comment Share on other sites More sharing options...

+-^CrossBow^- Posted February 2, 2023 Share Posted February 2, 2023 Just now, endor16 said: correct Pretty sure you shouldn't have any voltage coming off that until the console is actually powered on and sends the signal to the switch box to actually switch on and provide the full power down the cable. Do you get a spark when you plug the RF cable into the switch box as well then? Again, a multi-meter in continuity mode to check if there is a break in that RF cable quickly answer the RF cable question. Quote Link to comment Share on other sites More sharing options...
endor16 Posted February 2, 2023 Share Posted February 2, 2023 correct, power plugged into the rf switch box. spark when i plug the rf cable into rf port. forgive my ignorance on doing continuity mode. Quote Link to comment Share on other sites More sharing options...
endor16 Posted February 2, 2023 Share Posted February 2, 2023 (edited) just did a continuity test and get the beeps as indicated. tested from solder point of rf cable to other end that plugs into rf port on switch box Edited February 2, 2023 by endor16 Quote Link to comment Share on other sites More sharing options...

+-^CrossBow^- Posted February 2, 2023 Share Posted February 2, 2023 I just tested using my own 4 port switch box. And I can confirm that with my 5200 PSU plugged into it, there is NO power coming off the RCA jack on the switchbox because again, the relay has not switched over to complete that part of the circuit. So the fact that you are reading any voltage off that RCA jack on the switch box without the RF cable attached would indicate to me, that the issue is likely the switch box at this point. If it were providing proper voltage on the RCA then yes you should read about +12v off the solder points of the RF cable. Just to make sure when you checked the voltage off the switch box, you had the red probe in the center of the rca jack and black on the outside correct?

endor16 Posted February 2, 2023 Share Posted February 2, 2023 Yes. I have my rf box plugged in via wall socket and the the rf cable to the 5200 board. Without power to wall then yes I don’t have power on the rf box output. I’ll take a pic to ensure we are on the same page. Quote Link to comment Share on other sites More sharing options...

+-^CrossBow^- Posted February 2, 2023 Share Posted February 2, 2023 A white power cable? That isn't an OEM supply then I take it? What are the exact specs of the PSU you are using? Quote Link to comment Share on other sites More sharing options...
endor16 Posted February 2, 2023 Share Posted February 2, 2023 (edited) Funny. My oem power supply that was working went bad yesterday. This one is within spec. I have another on order waiting for delivery. Tested and works just fine on my 2 port 5200. Edited February 2, 2023 by endor16 Quote Link to comment Share on other sites More sharing options...
endor16 Posted February 2, 2023 Share Posted February 2, 2023 The above pics were out of order but I assume u got the just of it. Quote Link to comment Share on other sites More sharing options...

Yes, odd that the PSU you posted doesn't show the polarity, but I assume it is center tip positive? But to get back on point now. You are certain you are getting +12v off the RCA jack from the RF switch box when you have the AC plugged in and without the 5200 connected? Because...you shouldn't be.

endor16 Posted February 3, 2023 Share Posted February 3, 2023 (edited) First pic is me using the multimeter with just the ac plugged in and testing the rf port with nothing else plugged in. even with the original Atari power supply it did the same thing. the rf box came from a new old stock.
