CrazyBoss Posted February 1, 2016 Share Posted February 1, 2016 Hi. Is there any good points where to check the voltages of the ColecoVision PSU ? And what values should I get ? I suspect my PSU to be bad. Quote Link to comment Share on other sites More sharing options...
SiLic0ne t0aD Posted February 2, 2016 Share Posted February 2, 2016 I just plugged mine in the wall or plugged into the console, turned it on and carefully probed all 4 pins on the back of the plug, inside the bottom case.. there should be Ground, +12, +5 and -5 Volts.

CrazyBoss Posted February 6, 2016 Author Share Posted February 6, 2016 i tried the voltages today, dont think its a problem but I get around 0.50volts less like my 12v is 11.5 and the 5v is 4.5 can it be a problem ? - I think not....

+5-11under Posted February 7, 2016 Share Posted February 7, 2016 The 4.5V is low. At least some of the chips may not work with that low voltage. Quote Link to comment Share on other sites More sharing options...
