Grounding enhancement for our E30

[genozide]

Hi Sifus, Since our E30s have aged gracefully, there are areas where I suspect would have deteriorated or require attention. I am refering to the -ve grounding network here.Will it do harm or would be great if we provide additional grounding from body to the alternator/engine/etc etc ?Thanks in advance

No harm what so ever. Make sure you put copper grease to prevent oxidation.

Most earthing contact resistance will increase due to poor contact cause by oxidation or rust.

Suggest that you get are wire brush and remove the bolt/lug and give it a good brush to remove all the rust. applied copper grease before bolting back the cable lug.
