Overcharging problems

Key on, not running I get 1.1V from batt +ve to IGN #1 at ballast with everything connected.
Checked for voltage drop on -ve side with car running batt -ve to VR case, voltage was in millivolt range.
So issue appears to be a drop from ign #1 circuit? Blue wire and blue with tracer? Which one would be suspect? Of course it's just wrapped/tidied last year lol and gonna be ripping that out....
Thanks
Steve
