After a little bit of help trying to identify what this is.
I have been having a spark issue with my TB42S in my GQ
after chasing all the wiring in the ignition right through to the coil and Dizzy and replacing basically everything and the car still not wanting to fire i noticed that the picture below was the main problem this whole time.
but i have no idea what it is or what it does
so I'm wondering if i need it or can it be bypassed as this is the Earth wire that runs from the Ballast resistor to the ground on the engine block which completes the Ground circuit for the coil to the dizzy by the looks of it after i followed the wiring.
