Hello I am having issues with my geni / cut-out relay . I have a 32E geni rebuilt as a 6 volt as a 2 brush and the guy has rebuilt the relay as an electronic set up .I am not getting any more than 5.6 volts . Geni dash light won't go out . I have had 2 mate's check the wiring out one is an auto electrician and the other just as knowledgeable . Both believe the cut out relay is blown. My question is can I use a 3 brush cut-out relay onto the 6 volt system?? Cheers Rob

You can but need to convert the generator back to a 3 brush. Jerry -
First off, sounds like you're confusing the terms "relay" and "electronic setup". If it was the original 3 brush system, it used a mechanical cutout relay, connecting the generator to the battery when generator voltage was higher than battery voltage, and disconnecting when it was not, that's all it did. The charging rate (in amps) was fixed by the adjustable 3rd brush setting If it was converted to a 2 brush generator, which it sounds like yours was, then hidden within the cutout relay housing is an electronic voltage regulator. This little gem will control generator charge rate, based on battery voltage. It also has an electronic cutout, which is just a big diode that only lets current flow in one direction, out of the generator. The regulator would be specific to 6 or 12 volts. The downside to the electronic regulator is that it can be easily damaged if shorted, or connected wrong. If it isn't charging, first disconnect the regulator from the battery and the generator completely. Then polarize the generator by applying 6 volts + to the "RELAY " terminal and simultaneously grounding the "SWITCH "terminal as well as the generator chassis. Ideally, remove the generator when you do this and it should motor in the right direction. That will tell you if the generator itself is OK. After polarizing, reconnect it all and try again. Simply doing this may get it started again, especially if it's been sitting for a long time. If this doesn't do the trick, then you may need to find a replacement regulator. Not sure who is doing those these days.Comment

Also check cleanliness of all the connections. Corroded terminals can cause a significant voltage drop.Comment
