67 volt gauge pinout
2 Attachment(s)
I am trying to rework an old gauge dash and am planning to install a 67 volt meter instead of the amp gauge.
I saw one that used the noninsulated pin (top pin in photo) as ground and the left insulated pin (botton left pin in photo) as switched 12v. Makes one wonder what the botton right pin is for. Have I got this correct? Thanks |

Make sure to eliminate power from your amp gauge through the circuit board. pins #1 and #12 on the connector. Make sure they have no power with key on. Let me know if you need more help. I make volt gauge conversions kits for $100.00 plus shipping if interested. It will look like a factory volt gauge for a 67-72 truck. |

Also, the stud on the left (the one that is used for the +V connection) does not have any direct internal connection to the gauge. It simply connects to one side of the resistor. So this arrangement puts the resistor in series with the gauge's internal coil. |

Re: 67 volt gauge pinout
Another question. I looked about what I have to cut to install gauge. Beside cutting the ears I will have to slice off the bottom to match the original amp gauge I think to let dash light illuminate the gauge.
Can anyone tell me what the need of the 'hood' on top of the original gauges was for? thanks |

I have done what your doing before and it is a pain. My suggestion is the drill out the small rivets on both and transfer your stock amp gauge face to the volt gauge. I use 4-40 stainless screws with nuts to secure. It will set in the same spot as the volt gauge face but fit your cluster like it should. You can also use the stock amp gauge needle. You would need to apply power and ground, then meter that. I use a 10 amp battery charger and a volt meter to see what the voltage actually is and place the needle accordingly. What you end up with is a volt gauge set up that looks like a stock amp gauge. |

Thanks
I like the idea of having the printed volts on the face. I will try to tinker and use your suggestion as backup. |

If you need any, I may have some extra 76-87 volt gauge faces. I throw most of them out now. If I don't have any now, I will soon and you could mess around with some different ways to modify it to fit. From my experience, you will never get the gauge face to look right in the hole without cutting and moving the face on the gauge. Hope this helps you. Take care, Tom |
