So, as a follow up here...this is kind of an edit actually. Rather than ask for a schematic what I really need is a parts list for this. I can look at the unit and follow the circuit, I just can't determine 2 of the caps used in it.I bought the next model up, a GPS 750 , is it 'safe; to say the 2 mystery caps are the same? The newer unit came with a schematic sheet. The 2 caps in question are in the same location as the old unit.The caps in question contain these markings on them.
+100 / 63V
W. Germany
EBS-40 +85° C
The + symbol in front of the 100 I would take as an indicator of the positive end of the cap. What say the experts here?
