Was there a battery involved in this test?you are right. it is 2 batteries and 1, 2, and both switch. i connected the alternator to my table saw electric motor, run it and checked the output with multimeter. the reading was 0 volt.
George,Aaron, a 110 Amp alternator is going to rob a significant amount of horsepower out of what I'm assuming is an 18 HP engine. And it probably is overkill given a Group 27 battery bank. This will also manifest itself in poorer fuel economy. I experienced a drop in fuel economy when I went to a 120 Amp externally regulated alternator running on my 35 HP engine. So much that I'm looking seriously at swapping out to a 90 Amp alternator.
The alternator does not matter because it is the regulator that controls the field.... It depends which Xantrex regulator you have. If it is the Xantrex XAR then it is made by Balmar...Mainesail, Can I do this on an Amptech alternator and Xantrex external regulator? I do have the "small engine switch" - Do I continue to use that? (PITA to be continuing switching back and forth)
Don't run the alternator without a battery as load! You can damage the diodes.i retest the alternator with a dead battery and i still have a reading of 2-3 volts.
i received a new alternator - delco 110 amp 3 wires 12v, and when i am testing the alternator with no battery i get 27v. when i connect the battery and run the test, i get 0v.
You will blow the diodes if you run it without a load.Don't run the alternator without a battery as load! You can damage the diodes.
