Alternator question

Del when it happened it was on the highway both times. So I'm not sure. Kinda panic mode with cars all around lol.
I wanted to get it fired up and "wait" for it to die and investigate.
To test alt, should I remove field wire from alt or battery wire?
I will look into the bulkhead connectors.
I did the Mad bypass, but I can't remember if I got "rid" of the welded splice?
Thanks Del, square peg round hole with me and electrical...better grab a bigger hammer lol.

I would not even worry about the alternator/ regulator for now. Again, it sounds like something lost contact and you lost power. Do the "wiggle test" etc. Since you did the MAD thing, I'd start with the ammeter wire connections. Heck Steve it could even be a battery cable / connection
