Del Help! Cuda not Charging

You have found it, sounds like. This IS WITH the key in "run" right?

Something must have broken / disconnected.

The blue VR wire and one (blue) field wire are "ignition run" Sounds like this is your trouble. Sounds like you need to untape the harness up around the ballast resistor and see what they did. Maybe they just twisted wires together "in there"

The green field wire only goes on place.......from the remaining field connection to the green on the VR.

Make SURE the VR is grounded
