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.
