I have been having a problem with the battery voltage dropping below the low level threshold when I have moderately high current draw.  Since up until now this has only occurred when gear is extended or retracted I have not bothered with it until now.  I recently added landing lights and discovered the problem occurs with landing lights on while on approach.  I have recently removed the alternator (for another reason too lengthy to explain here) and began investigating (again) this issue.  I have an older model L60 (60 amp) ND alternator from Pelican Aviation with an LR3 Regulator from B&C.  The label on the alternator indicates that it has a built in regulator.  The write up in ACS catalog for the regulator indicates that it will not work with an alternator that has a built in regulator.  The alternator has clearly been working to some degree as I have about 80 hours on the plane.  However, something is not right because I should not be getting a low voltage alarm under these circumstances.  I am considering buying a new B&C alternator.  Unfortunately I don't have anymore data and the airplane is now sitting without alternator.  If necessary I can put it back on and get some more flight data.  Does anyone have any ideas on this problem?  Any help is appreciated.
