    I know you switched stuff around…maybe  try a ohms test from boot to engine frame body.   stabalize the reading (low ohms)  and  start wiggling stuff around

    check for sudden drops in continuity.  needle meters  are best for this as the needle swings react faster to ohm changes on digital meters (JMHO)

    do same OHMS test  from  mag plate  to engine frame  as you rotate  the mag plate  or wiggle it… ground continuity is essential
