Title: Earth lead on battery
Post by: Iain on 19 February 2010, 21:57:48
I got a message on the computer today saying headlight was out,so i lifted the bonnet to see if it needed a wiggle....when i put my hand down to the back of the headlight(Battery side) i noticed that the earth lead was red hot!! :o
It was not the brown wire but the one which is encased in the plastic, nearest to the front of the car....

Is this meant to get hot!??  :o

check all earth wires under the battery and the one in the corner next to the light and battery, wire will only be hot if there is a high drain on the circuit, also check that the battery is not getting hot aswell.

No, should not get hot, but is a definate tell tale sign that you have a dodgy earth joint somewhere. Be very meticulous when cleaning up the connections at each end, and the crimped joints are known to fail, which could cause a similar fault.

Give it utmost priority in sorting it out, and I would advise NOT to use the car until you have done so.

Once you have found the bad connection or dodgey crimp put vaseline/petroleum jelly on all the earthing points, prevents corrosion & water ingress in the future.
(Do not use grease) :y
