Where is the neutral/earth on the f12 cars?

[cartaa100]

Hi guys,

Sorry very nooby question, however I've just installed a jb4 for my 640 and I'm occasionally getting drive train malfunction and occasionally stalling when coming to a stop.

I have it currently attached to the washer bottle bolt as it seems to work better than the strut braces...

So the main question where is the neutral terminal/earth/ground??


THANKS!

Use a circuit tester (not required)
however usually anywhere with bare metal is a good ground, just take off a bold sand under the bolt and around the area

reattach the bold with wire in that area and it'llw ork just file

Why do you think it's the earth? Have you done logs and scanned for errors?

Will be logging on Monday, the reason for thinking its the earth was because the car would run better when earthed in different areas
