Can someone tell me what it is for, all i know is it gets rather warm.
I noticed the other day that one wire was off, would that cause any damage?

Dunno what coil you're on about but resistances do tend to get warm..

It's the one on the battery side, RHD, it had 3 wires going to it and has an open coil of wire protected by a metal cage

| I was told it was for the main beams. I disconnected one of the wires and true enough, no main beams. Have no idea why its needed though. |

Thats so weird and funny you should say that. I only noticed that one wire was loose after i had driven it at night with my full beams on, it might be that it needs to be totally disconnected for it to affect the lights.

Think it was random alfa electrics, I have been told that it is to do with the speed control for the heater. The same thing is used on other cars including fords, I was shown one by my bodywork guy.
So basically its a variable resistor via the speed control in cab.

I thought it was the ambient air temperature sensor for the EMS.

Engine
Management
System
i.e. what ECUs used to be called before every car had one and, IMO, a much better term and I'm a bit 'old schoool' anyway.
