Subject: Tech: Tron Power Testing : Questions (some dumb)
Date: Sunday, February 27, 2005 12:16 AM
I tested the voltages being output by the power supply PCB. Overall they
look fine. There are two a bit out of range;
Schematic Label: Coin door lights
Schematic Voltage: +12V
Recorded Voltage: +10.62V
Schematic Label: Coin Meter
Schematic Voltage: +5V Unreg
Recorded Voltage: 10.28V
Any ideas as to what might be causing those?
Also, some dumb questions about a few of the schematic notations: Note the
"J4"and "J5" indicate the connector, the (letter/number) code indicates the
position as noted on the tables here:
http://home.earthlink.net/~rescuetron/docs/pstest.htm
"A.Grnd" - From J4 (A4) - (Is that 'all ground'?)
"V.Batt" - From J4 (A5) - (Something battery?)
"Logic Grnd" - From J4 (A2)(B3)(C3) and J5 (B4) - (Special Ground?)
"Reset" - From J4 (C3) - (I heard a rumor that this wire was key?)
"Unreg" - From J5 (A1) - (Unregulated?What does that indicate?)
