Bypassed AmMeter on 63 dart, now I get nothing

Sorry, man but from your description I've no idea what you did or why.

Does it have mostly factory wiring, and is it kinda, or mostly, or not hacked up?
Do you have a factory service manual?
What is "AM?"

What do you mean "re ran wire?" What wire? And from where to where?

I'll have to look, as some years of the early girls don't really need a bypass because the bulkhead connector has better terminals for the ammeter. This does not mean that in some cases the ammeter might not be damaged, etc

This is the link from MyMopar for the aftermarket wiring diagrams. They do not show a 63 factory manual there. You have to download these, "unzip" them, and pick the ones that fit
