Thanks mike and Martyj ill take a closer look later tonight.

Yes studley I have no idea. Everything I've learnt is self taught or I pay someone to fix and I'm not very mechanical/electronically minded. A coil issue was suggested to me by someone off forum hence why I asked.

So thanks studley for reinforcing that I have no idea. I may as well give up trying to fix things myself and either sell the pin or pay someone to come fix it. Thanks for your encouragement.

Cheers
