Thanks guys, I assumed it should be practically the same but wanted to make sure I wasn’t missing something.

I had no electrical issues, then my alternator stopped charging. Swapped regulators, no change. Installed an OEM single field round back alternator (should be 35 or 46 amp) and it charges about 20 amps at idle. Swapped VR back and still 20 amps at idle. Tried another old oem 35 or 46 amp and still 20 amps charging at idle. I cleaned all connections and looked for obvious issues and high resistance among any wire runs, but I have;

14.55V at alternator
13.94V at ammeter
13.82V at sensing wire (blue VR wire)
13.55V at battery

Obviously have an issue here somewhere, but its odd that it started with the alternator apparently going bad. Tried another battery, and bypassing the ammeter too, same deal.

Now I need to pin those needles, got to feel that heat
