Its generally the battery that fails.
I waited two and three quarters hours for the breakdown service to arrive,they changed the battery and I was up and running.
If your a short walk from a Timpsons shoe repair outlet, ask them if they could check(or replace your battery)
I was a short walk from Timpsons and if I had known I was going to wait that long. Timpsons would have been my first port of call.
Keep safe and have a good Christmas
Sewing on Girl Guide badges, aaargh!!
