Hi guys,

Thanks David, I'll check the relevant colors.

Just a brief update for the green related (a.o.) wires I've thoroughly
cleaned both male and female connectors with chrome cleaner.
I've used Q-tips as advised and guess what - these really got absolutely
I've put these Q-tips into my battery powered screwdriver unit and got the
tip turning quickly - the contacts are like silver shiny now...

The next moulded connector is to be treated similary tomorrow...

When driving the next time I'll do some temperature measuring again....
I'll keep you updated...

Hello, Hans.

This may have been said before but I've been a bit busy to follow this
Generally, heat = resistance and corrosion can be a cause. But then again,
heat is produced by high current; you might expect some heat from headlamp
wiring (brown, blue/red and particularly blue/white).
You won't have to bypass the connector group if it is a multiplug-just
separate it and clean the male and female connectors.
Incidentally, have you ever touched an old-type (Dash Mounted) Lucas
ignition switch when the lights have been on? They get *hot*, which is
presumably why they have a ceramic insulator.

Hope this helps,
