Hi Guys,
The new relay fixed the problem with the indicators and binning the Dim Dip unit sorted the lights (I would never have found that!!). Thanks for all your help and advice, it's much appreciated.
Cheers and best wishes, Dave

Anton, Thanks, it'll stay in the bin then!!! Cheers Dave

Thanks for the link Anton, it 'kind of' makes more sense now!!
Cheers, Dave

Great, Thanks Robbie, Cheers, Dave

Hi Robbie,
I'll let you know if the relay does the trick. Just one question, do I need to replace the Dim Dip unit or can I just carry on without it.
Thanks again for your help, Cheers Dave

Hi Jordi,
I checked everything as best I could and all seems to be ok. The only thing I can't check is the relay so I've ordered a new one on eBay. I'll find out in a few days. Thanks again for all your help. I'll let you know what happens,
Cheers and best wishes, Dave

Jordi and Robbie, You made me think that I may have had the wrong unit. The one I disconnected was immediately above the the fuse boxes and from your last post I thought you were expecting more than 2 wires, so I looked on the passenger side and could see another unit with a plug in of about 5 wires...

Hi Jordi,
There was 3 wires including one to earth (Black), the other 2, one green the other Y/G I disconnected.
Cheers, Dave

Hi Robbie,
No good I'm afraid, Apart from the earth there were 2 wires one G and the other Y/G, I disconnected both but problem still there. Thanks again for the suggestion.
Cheers, Dave

Robbie,
Thanks, I'll give it a go. I could see the unit but had no idea what it was. The unit and the fuse boxes are not in what I call user friendly positions.
Cheers Dave
