Well chaps
Thanks for all your help
It’s fixed
I had all but given up but my eldest son was nosey enough to try to prove his technical superiority to his apallingly incompetent father (despite me funding his every second of life)
Anyway together we worked out that it was that the central pin not being gripped by the hole in cardboard washer isolator ring so that the central pin was just getting pushed back further in the fitting and not coming forward with the spring when the lamp was located
Have to say you have all been right in that the fitting is pretty rubbish
Anyway after both of us fiddling with some long nose pliers we thought we had solved it but when I turned the hazards on to test, all the indicators went dead, as we had unwittingly shorted the fitting and blown a fuse
Next came a very frustrating half hour as we realised the fuse box diagram printed on the fuse box cover was wrong (it actually turned out to be back to front) so we had to take out every fuse to see which was the indicators
Every fuse was intact and everything else seemed to be working
Extremely puzzled
It turns out it was one of the 20 Anp dash fuses in another small fuse box and not the indicator fuse which had gone
Anyway we fiddled on again and finally got the central pin through the hole in the washer and got it to sit on top of the spring with enough grip to spring back
Slowly put the lamp back in and it works
Took the Mog round the block and over a few bumps and it’s working fine
What have I learnt?
1. That my 19 year old son is good for something
2. Morgan front indicator fittings are rubbish
3. My patience isn’t what it once was
4. MMC put my fusebox in the wrong way round to their diagram
