Earth wires
I have for many years found bad earth connection on my series 2 16v turbo resulting in no head lights, indictors, fog lights due to the earth connection at the front below the front lights and one time bad / no fuel supply due to the earth connections in the boot being loose. Then looking at the circuit diagram to find the fuel ecu and the ignition ecu are also earthed at the front. Bad starting? poor tickover cold/ hot? changed water temp sensers? airflow meter? need i go on. Recently my car started to tick over rough this being diagnosed as poor injectors performance, yep you guessed poor earth connections at the front. May be in warmer / dryer countrys these problems don't happen. I now will be replacing all my front and rear earth connections with standard pre insulated spade connectors. Note. before going to the earth faults always get the engine compression tested then you know the engine is sound

Paul,
Do you know if the earth/cables on the Thema are bog standard ones? Last week I removed a negative battery lead from a Rover 400 (at local scrapyard) and am plannig to swap mine for that, however they look quite different. The one on the Thema looks much thicker and is green as opposed to black.
Cheers

Re: Earth wires
Assuming (dangerous) that all 8v 16v v6 s1 s2 s3 are all the same, i have never seem a green battery earth wire. I have only seen black earth leads which run fron the negative side of the battery then to a bolt behind the battery, fixed to the inner wing and then on to a bolt on the gear box housing. The bolt can be seen if the front inner wheel arch liner is removed. P.S as there are two paul,s on this site i will in future be paul.o

Re: Earth wires
Paul,
The setup of the wire is as you describe, however, the wire is covered by a green plastic instead of a black one.
I am 99% sure this is the original wire (we've had the car since new). It also seems slighlty thicker than most other -ve wires I've seen on any car.
The car was delivered in Belgium, maybe it was different for the V6s or maybe it was a Belgian market thing?
