Yes you did. That's why I called you out. or what do the yung uns say "A shout out"
Of the things I did, that seems to be the most likely.
Next most likely is the battery charging. My understanding of the SI alternators is the field gets power from whichever is higher voltage, the battery or the diode trio. So my thinking is if the battery is low, the field never really develops any strength.
Not saying my understanding is correct.
