switch failure

[Tony Stillman]

Wayne:

That's kinda backwards!  Most regulators will not fully regulate until they
have some load on it.  That is, if the regulator is supposed to be a, say,
5.1v, it may be at 5.3 or 5.4v until it gets roughly a 100 ma load on it.
Then it will lock in at 5.1v.

I suggest that you need to send it back to the manufacturer for replacement!

tested 5.97v which is where it is suppose to be at.  However when there is a
load on it like with my expanded scale meter it would only put out 4.2.  So
it seems the regulator is not regulating properly but only when a load is
put on it.
