68 Valiant dies and runs lumpy, then suddenly runs fine.

I tried the alt gauge bypass, and no dice. Same symptoms, but without the alt gauge, the left turn signal indicator light on the cluster wouldn't turn off. Put it all together as it was before, and didn't find any indications of a short.... EXCEPT a white wire going up the column that had rubbed through. I have a feeling this is where the sparks came from. I wrapped it up and bundled all the wires going up the column with electrical tape.

Still the same symptoms, but no sparks since.
I'm going to invest in a multi-meter after christmas and get to the bottom of it.
