I was out driving in my 1915 Model T a few weekends ago and it suddenly stopped running. I knew the fuel level was low in the tank; I was going up a hill - so I assumed it was a fuel issue. Yesterday I cleaned the fuel lines etc.

Car started on BATT okay as usual - I thought the problem was solved. But when I went to switch it over to MAG it cut out. Flicked it back to BATT - all was fine. I have removed the coils and dismounted the coil box. Took apart the front switch, cleaned it up and tested the circuitry. Cleaned the connections in the box and at the rear and tested the circuits again.

So I am positive that all is fine back to the Magneto contact assembly. Question - as my next step will be to remove the Magneto Contact assembly and check it out - how do I ascertain that this may be the problem? What do I look for? Do they wear out over time? And then just suddenly fault?

Any thoughts gratefully appreciated.
