Recently acquired '19 Model TT without electric start does not seem to fire the plugs upon cranking. This is my first T without a starter/battery. I'm not sure if the mag is working. Two question please - 1.) Simplest methods of checking for mag output,and 2.) if mag is not working, can I install a battery, either temporarily, or permanently for the singular purpose of ignition?
Thanks for help.
Dennis, my family owned a 1924 TT truck that they used to operate a cotton gin. The truck was bought without the starter option. A hot shot battery was used when the TT was hand cranked. When running the switch was turned to Mag.
A 6 or 12 volt battery could be used to get ignition during cranking. I have used motorcycle batteries for this purpose (cheaper)
You hook the positive (+) terminal of the battery to the coil box terminal lowest and closest to the carburetor as shown in this diagram. The negative (-) terminal is connected to the frame.
Dennis,Are you using 4 or 5 notches of spark advance when cranking on mag?? Not the same as a battery start as on mag the timer needs to be in the right place when the power from the mag is there.Mag starting is not to be confused with battery starting.Bud.
Do as Royce suggests, then fire it up on the battery. Once it's running switch it over to magneto. That will tell you in a hurry if the mag is putting out enough or not.
Thanks for the help. I have a 6v battery from my T Touring that I replaced with a new 8v bat. Will try to remember to let you know how it goes ..... When I get a round tuit.
