Q.What is an isolator used for?
A.They are solid state devices which allow electrical current to flow in one directly only. This allows one alternator to be connected to multiple battery banks without fear of fully charged batteries discharging into undercharged batteries.
Q.How do I know which isolator I need?
A.It all depends on the number of alternators you have, the amperage output of the alternator(s), and the number of batteries that you are wiring to.NOTE: Professional Mariner Isolators are not recommended for use with the following alternators: Niehoff; Delco 10 SI type 116, 25 SI or 30 SI series; Hitachi LR 135-31 type, 110 or 106 type; Leece Neville JB series; or any self exciting style alternator.
Q.How do I wire up the isolator?
A.ANSWER: The isolator is wired between the alternator and the batteries. You would have either one or two input terminals that connect from the alternator and either two or three output terminals that go to the batteries.
Q.There is no output voltage on my isolator?
A.You can check to see if the isolator is working with a digital multi-meter set on “DIODE CHECK” mode. Put the red lead on the alternator input terminal and the black lead on one of the battery output terminals…..you should get a reading around .4 on most meters. Then reverse the leads and you should get a reading of infinity. Perform this procedure from all of your alternator input terminals to all of your battery output terminals. If you get a different reading with the red lead on a battery terminal then the isolator is defective.
