Hi Kevin,
As long as the new cable is capable of taking the full current (reduce risk of fire if other earth goes open circuit) and it goes on the engine block then it should be OK. Ideally you would be better cleaning the original earth point as I am not sure if other electrics use the chassis as an earth return as on a standard negative earth car.
Good luck, hope it all works out. You never know, this connection maybe the cause of all your electric woes..
Nick.
p.s. I repaired another ECU and this time I took some piccies. I'll make a document on how to repair it and post it here when I get the chance.

Funny you should you should ask, I have been looking at the problem again
today and found that the voltage drop is in the earth connection lead from
the engine to the frame to which you cannot access ( the bolt is ontop of
the crossmember where the engine sits). The volt drop is about 2.5 volts
is'h.

Assuming that the current drawn on cranking is 400 amps and assuming a full
12 volts would mean that the resistance of the starter is about .03 of an
ohm. As I am dropping the 2.5 volts on the earth side means the resistance
is in the order of .0075 of an ohm, which is not bad considering. I have now
bought a new earth cable which will go directly from the battery and bolt
directly on to the starter motor housing. I will also be leaving the
original connections in place.

I cannot get to the car to try this until next weekend but I think (hope)
this should fix the problem. I have spoken to other people who all seem to
say there cars crank slowly I will let you all know if this is a good fix.

I envy your drive, mine should be ready over the next couple of months.

Hi Kevin,
Did you get the starting problem sorted out?
It might be worthwhile putting some threadlock on the bolt threads and/or
double nuting it to prevent it coming undone.
I'm repairing another Idle speed ECU this weekend....gives me an excuse to
'test' it by taking the 'D' out for a long drive.......shame eh?

Just to update those people that gave me advice on fitting the steering
bush
that Martin got for me.

Started last night about 4.30 and finished at 6.30 with just the knee pads
to fit all went quite well without any major problems.

Except, I am very glad that I did change it as during the process I
discovered that the pinch bolt on the lower steering shaft had never been
tightened. The shaft was just floating around on the splines held on by a
wing and a prayer.

I had driven the car back from Birmingham 150 miles with the steering like
this!!! and could have lost the steering completely on turning the wheel
to
hard. I will now be checking all steering and wheel components before it
goes on the road again.
