I’ve finished to assemble the MoBo yesterday evening and bought a PSU this morning. My first power supply test (without ICs inserted) gives me these measurements:
Green point = +4.94 V
Yellow point = +4.94 V
Red point = +7.93 V
Blue point = -7.88 V
My PSU is rated for 660 mA max.
I’m looking for tips and advices … ?
What are the voltages on each pin of the MCP1700? Other voltages are within tolerances.
MCP1700 left = 0 V
MCP1700 center = +4.94 V
MCP1700 right = +3.28 V
viewed like in the Power supply testing schematic in the “Ambika – Motherboard assembly instructions” webpage.
Given that MCP1700 right pin is connected to the yellow point, I would suggest you to check your measurements again.
I’ve re-heated the solder joints on the C8 and C10 caps. Now I have +3.28 V on the yellow point !
Many thanks Olivier for your help ! Really appreciated !
