However, when the car is idling (700-800 rpm) the charging voltage drops down to around 11volts. If the car is left idling too long or the battery is old and it is very cold out (Canada eh)... the car will konk out.
I have talked to the dealer and they know about this problem on older SVX's even with new Subaru rebuilt altenator's. But they don't know the solution.
Has anyone ever experienced this and found a solution? Let me know.
Thanks,

I have no experience of that sort of cold
, may have some effect. The 14V above 1000rpm seems normal, the 11V at idle is not. When the engine speed is below the charge speed of the alternator, the system relies on the battery, which should be 12.2V when it is not being charged. For it to be 11V either the battery has a large load no it, or it has a bad cell.
