Sapphire 2.0 DOHC Ghia manual.

Noticed the earth strap from gearbox centre mount to body has parted, I am going to sort it of course but what purpose does it serve as there is a chunky engine earth from bellhousing to battery just inches away?

I expect it is just belt and braces....useful if the engine one had failed?

Cheers, I thought that but had noticed the main earth gets warm when cranking, maybe the gearbox earth help share the load?

That would make sense, I am glad I saw this post as I don't have one on my car...I will fit one now

It don't need it and they was not fitted to a cos as standard. I think the gearbox one is on some models to help with static shocks etc.

Not needed I've never seen that they serve any purpose on my 2.0 sierras
