1940 Alternator Conversion Question
When converting 1940 Sedan to a 1 wire 6 volt positive ground alternator what do you do with the wires at the original regulator. I still want my battery gauge and etc to operate. I understand I will need to run a new heavier wire from battery to the alternator.

Re: 1940 Alternator Conversion Question
You should be able to still use the "B" terminal on the voltage regulator as a terminal to connect everything to. The other two terminals would not be used (the "F" & "A"). The voltage regulator is not functional, it is just a convenient place to connect the wiring, so the other wires would be disconnected or if you still want the wires on the VR, terminal the other ends of the "F" (Field) & "A" (Armature) wires so there is no possibility of them making contact with anything.
BTW, I'm not a one-wire alternator fan. A lot of people like them, but to me, things just work better keeping it three-wire. And it is not that much different to install, but that is just me. |

Re: 1940 Alternator Conversion Question
When you switch to an alternator (the most common ones) the regulator is internal to the alternator. So, the existing voltage regulator can be removed or used as a terminal to connect the alternator and battery (etc) wires to. But it serves no function other than setting there. I just don't like the way the one-wire alternator function, but like I said, that is just me.

The original wires could be left connected to the firewall mounted regulator? |

Re: 1940 Alternator Conversion Question
Just a suggestion, I took the regulator off and cut all the connecting wires from the battery terminal. Just a feel good thing,maybe over going. Al
