Failed earth connection between engine and chassis. It's using the stop
cable as a substitute.

It might be a simple case of dirty connections or the (usually) braided
cable earth has 'died'.

Definite diagnosis -engine/chassis earth not working so starter current is
trying to go through the controls. Find the engine to chassis earth strap
and unbolt both ends and clean them, or alternatively run a new heavy earth
strap from chassis to engine or gearbox.

Similar near-disater happened to my first RRC. It had twin batteries
wired in parallel and Goodrich SS brake hoses (which is relevant!). The
clips securing the +ve strap from battery to starter solenoid broke
allowing the strap to become entangled with the steering column. After
a while the column wore through the insulation on the strap. Very odd
that at full LH lock the engine almost died and the lights dimmed.
Arriving at my destination I was surprised by the smell of burning
plastic. Rapid bonnet lifting revealed a surprising amount of smoke
followed by rapid battery disconnection, I retrieved the vehicle the
following day and found that part of the loom to the rear lights had
melted and the throttle cable had melted the plastic in the Bowden
cable. A large amount of new wiring, a bicycle brake cable as
replacement throttle and a pair of those instant battery disconnect
clamps from Vehicle Wiring Products saw the vehicle back on the road.

A few weeks later it was being tested for it's MOT when one of the
Goodrich hoses burst. We found that the plastic liners had melted in
all five hoses and concluded that they had offered a good-ish earth
return (but how?) during the wiring fault.

I mentioned it to Goodrich who were horrified and sent me a replacement
set. They said that they were going to include a warning to ensure that
earth straps in RR were carefully checked when fitting their hoses.

I've heard of speedo cables failing soon after similar mishaps as well
were the earth has chosen that route.

You might want to take a look at a similar thread last week.
http://shortlink.co.uk/44f

From advide here it sounds as if my SIII also has a bad earth. The electrics
refuses to take any more current load than the charge and oil pressure
lights. Any more and it dies completely. I'll be checking all the earth
leads this Sunday to find out if they were right. The starter has been very
slow to turn recently and a feint hot/burnt smell has always come from the
engin bay after starting.

Good luck with your,
David
