Re: regulators
Not familiar w/those ones. The ones made by "Fun Projects" work great, lot's of the Model T peoples use them.

Re: regulators
I'm familiar with Fordbarn member Tom Wesenberg's EVR that replaces the third brush inside the generator. Affords keeping the original cut-out with no visible alterations.

Re: regulators
I'm also a big fan of the EVR made by our very own Tom W.

Re: regulators
Tom W's regulator has an advantage over the other type of regulators. While both regulate the voltage to the correct value, they do it in two different methods.
Tom's regulates the field current to make the generator produce more or less power depending on car's need. Thus, when you don't need much power, you don't produce much power. The other types use a "shunt" or "series" type that can waste power to keep the power to the car at the proper value. The best method is to vary the current to the generator's field coil to make the voltage constant. Marc |

How you you recognize that your cut-out has failed? Can you see it on the ammeter as a high or low reading? |

First, lets understand what the cut-out does. The cut-out disconnects the battery connection to the generator when the generator's voltage is almost lower than the battery voltage. Its a switch that should allow the generators power to flow only out to the cars electrical devices. It should prevent the power flowing into the generator when the generator isn't turning or producing very little. Its a one-way device...hence a modern diode can replace it. The cut-out doesn't regulate the voltage. Thus, a failure of the cut-out will cause power to flow into the generator either at the wrong time (motor stopped) or not at the right time (generator making power). Marc |

Re: regulators
Thanks Marc,
So I suppose it could fail either way. It might not close and allow the battery to be charged/maintained, or it might not open and drain the battery through the generator when stopped. Either way a dead battery would be the result, and maybe generator damage too...is that right? My ammeter shows a positive charge most of the time, with no more than a 10 amp max. |

Re: regulators
I have had one of James Peterson's regulators on my '31 Roadster for about 12 years - No Complaints! Works the way it's supposed to.

Re: regulators
I am using this one from Mac's:
http://www.macsautoparts.com/ford_mo...ound-only.html Been using it for several months now, couldn't be happier. Works as advertised. |

Yes, you are correct about the results of a bad cut-out. Marc |
