Something fully mangin'
Some of you may know that my car has been giving me hell lately and leaving me stranded at the worse possible times. I replaced the battery and then the starter motor to find out it was just a stupid earth problem all along :bang:

Where are some good places to create more earth points from the engine to the bay and how would I go about this?

Also, my alternator gives a correct reading of 14v, but when the engine is revved it jumps around anywhere from 6v to 16v.. Why? :whistling

Cheers boys

If its jumping from 6-16v its shagged, either the alternator or the regulator. It should read a constant 14.8V even at idle, occassionly they read a little lower (not lower then then 14) at idle. If its jumping around that I would be trying another alternator and reg. Are the cables from the Battery to Alt in good condition? and joined firmly no corrosion?

Sounds like you could have a dodgey sensor wire too, the thin wire that goes from the alt to the battery, try replacing that with similar gauge wire, even just as a temporary thing and see if it settles.

Convenient earth points on the V6 are mostly in inconvenient places, there is a nice thread on top of the tensioner assembly that suits well for a single 4ga to the master cyl bracket though. :) (close to alternator cable can be hidden under the top radiator hose for half its journey, and the assembly has multiple bolting points to the block, perfect)
