Just rewired 54 ford truck with an original wiring harness and 12 volt conversion. Everything works except my battery light stays on all the time. When I ran wires to the voltage regulator and had one to the armature and one to the field terminal and one to ground. There was not one to go to the battery terminal but I was told to run a separate wire from the battery terminal on voltage regulator to the B terminal on the light switch. Is this correct;

 

I trust you have the correct light bulb socket insulated two wire.? If I remember
one wire (on bulb) goes to 'Ign" switch and the other goes to Arm on the regulator,
so when engine is stopped key on, the armature acts as ground and lights the bulb-
engine running, it acts as B+ and now bulb has two B+'s light goes out....

 

Thanks Big Job. I went and checked and I do have one wire from bulb going to the coil terminal on ignition switch and other is on armature terminal on voltage regulator. I know the generator is good new wiring and voltage regulator is also new. Does any one have any other suggestions.

 

Have you polarized the Generator lately?
I forgot how but others here can walk you
through it.

 

I tried after finding how to do it and hope I di it right. What I did was take the field terminal off and touched it to the battery terminal on the voltage regulator for just a millisecond and got a pretty big spark. What I had read it should just have a blue spark but this had a pretty good pop. As I had mentioned do I really need a wire running from battery terminal on voltage regulator to b post on light switch. Any opinions would be appreciated.
