Voltage gauge in dash question/not working - Third Generation F-Body Message Boards

My voltage gauge doesnt work. I swapped out the alternator when it was bad. Could using an 84 alternator for carb be affect to the gauge. I used an 83 amp alternator from a 84 carbed firebird because the the 85' trans am 105amp alternator bolt holes didnt line up. (I figured out years later that i could take apart the alternator and rotate the front and rear backing molds to make it bolt up the right way,) but until i do. is my theory right about how both alternator are wired differently. i checkd the wiring diagrams and they are way different. I answered my own question huh

The type of alternator cannot disable the voltmeter.

Happy Racing!

Fog lights are not driving lights. They look dorky. Turn em off slow pokes.
