make sure all your earths are clean and eveything has a good clean contact

[Mr.AdamB]

possible an earth has come loose.. i had all sorts of weird thigns foudn a loose earth and they all went away... tis comming loose again and there comming back so. look at ure earths make sure there tight.

Check your belt is correctly tensioned
Then go on diagnosing outputs etc.

[andreas395]

where are the main earths on this car

[Wobba]

Tbh as arj says, make sure belt is good and tight first.

If not or if you need a new one I think it's been covered a few times how to replace and tension aux belts.

There's a bit earth at the front of the car by the gearbox.
