Dimming lights

[MadMacMcMad]

I am sure lots of us suffer from this, but what is the main cause of the lights/general electrics dimming occasionally. Probably due to additional load when the fans cut in etc. So it's either a bad earth or supply. As it is a common problem there is sure to be a common remedy and this post could save me a lot of time.

The probable cause is an extremely high resistance in the battery wiring harness from the central junction box (under the bonnet) to the B+ terminal on the alternator. To rectify the concern an additional cable should be installed.

See Parts thread for part number of cable."
