Earth Lead

[Zedman]

I have just completed a rebuild on the 305 Chev engine and re attaching 'bits' and thought I'd re attach this Earth Lead.  When I commenced dismantling my 1981 Avanti II, I took plenty of photos and annotated them because I knew if I didn't, I'd pay one day.  In this case, a white Earth lead attached to the right hand rear-most  inner side rocker cover screw was discovered disconnected when I first found it sticking upward. From it's shape, I bent it, it looks like it simply attaches to one of the bolt holes in the rear of the same Head.  Can somebody confirm the attachment point for this 'loose end 'please? Can't upload a picture because I'm apparently over my limit...

IM NOT SURE THIS IS WHAT YOUR TALKING ABOUT BUTT....

ALSO THE GROUND FROM THE NEG. BATTERY POST IS CONENECTED TO THE A/C COMPRESSOR BRACKET 

I INSTALLED TTHE ONE PICTURED WHEN  I ADDED THE 700R4

HOPE THIS HELPS

It's just a ground wire that you can attach anywhere on the engine cylinder head or engine block.

I've noticed at least two other Earth connections... one on the RH engine mount to chassis, and another from the Transmission to RH Chassis rail (somewhat like you've shown in your pic).  I guess my white earth lead is there to mitigate the inherent insulation of the head gaskets.

Thanks, that confirms my assumptions. 👍
