Title: Very weird Electrical problem, you won't believe this one !
Post by: petergalileo on February 01, 2007, 17:40:33: Go to start the car, symptomatic of flat battery, stupidly replaced battery. Held the ignition in the start position while wiggling the auto gear selector (thought it might be that), noticed smoke comming out from beside the hand brake, quickly removed electric window switches to have a look and saw smoke comming out from the handbrake cable !

Released handbrake and the starter works fine. If I pull up the handbrake same thing happens ??

I now need a new handbrake cable as it must have a rubber liner and isn't smooth in operation anymore, but what the heck is going on ??

Any advice would be appreciated, this one has baffled me to the extent where I am thinking of hiring a priest just in case the thing is possessed !

Its an N registered 300TDi Discovery ES and has the later 300TDi engine with EDC. No other faults on it.

Thanks in advance (I hope !)

When you release the handbrake it's probably earthing through something else.
