I`m going to be trying to start a 1915 T, for the first time. Has not ran in three years. Will the magnets need to be charged? What do I need to do befor starting, other than carburetor and fuel.

If the mag was OK three years ago, it's probably OK now. If it's not, you can start and run on battery temporarily. It will run that way for quite awhile, but eventually you'll need to charge the battery. Of course, if the mag is working you can use it to charge the battery for starting. If the mag is really working you don't need the battery at all.

Some of this won't apply to your 1915, but here's Milt Webb's "Mothballs" checklist: http://dauntlessgeezer.com/DG93.html.

I sure thank you, I`ve never tried starting one that old.

If you run into trouble starting it at first, don't worry. You can make it an easy starter. https://www.youtube.com/watch?v=6ZzX1Wwrkq8

:-)
If you don't have a battery close by (a friend of mine uses his cordless drill battery for cold starting his '25 TT), a battery charger will do the trick if unsure about the magneto. I used to set mine on low charge until I bought a $20 dollar battery. Works good.
Don't let that magneto get any DC voltage from any outside source.
If your switch is good, you'll have no troubles. IF I have my head on square, the mag post is on the drivers side and the battery post is on the passengers side.
Check first. :-)
Cases in point; the '23 engine in my '18 sat completely dormant since the early 90's or earlier. The mag is strong with this one. Stiff upper end with a loose lower end. Starts fine on the mag.
The '19 engine (completely worn out and may have been dormant for 50 years) in my Crappy '24 still has life in the mag and I used to light the head lamps with it.

The other hand; the '26 engine in my TT will not even run on the mag once started. That one needs a re-charge.

Perhaps some two cycle gas to aid in starting or a shot of oil in each cylinder to help it along or just keep cranking with the throttle open some more, it'll go.
Please report back about how it went to start that '15. :-)
OH! How does the commutator/timer and roller look? Clean?

If I jump start T with a 12v. bat. Duey are you saying to disconnect the wire coming from the Mag.

No. Not necessarily; if the switch on your coil box is working.
The passenger side BAT post will serve. Does your '15 have a battery post like the pic below? The red handled battery charger clamp is attached to the Battery terminal of the coil box.
The MAG terminal is on the drivers side of the coilbox.
Mine's an '18, should be very close to the same as yours.

Do you have a pic of your coil box connections?

Aha. If you turn your switch counter clockwise, you are on the magneto and if you turn your switch clockwise, you are set to battery, yes?

Mine sat for 2 years and I just got it started and drove it for the first time today. Of course after so long in mothballs, the carburetor needed to be rebuilt and the float re-set and my sediment bulb screen replaced. Mine had gas in it, much of which evaporated leaving an inch of smelly liquid in the bottom so I had to drain the old gas out of the tank and flush it clean with a couple of gallons of fresh gas.

If yours had gas in it, the tank will need to be flushed of the old gas and new gas poured in. The sediment bulb screen might need to be changed as well. Good luck. Jim Patrick

Steve, did I read this correctly?

"Of course, if the mag is working you can use it to charge the battery for starting. If the mag is really working you don't need the battery at all."

I think you need to explain how the AC from the mag will charge the DC battery. Sounds like a "fun project":-)

Yes, John Regan sells a magneto battery charger for the earlier cars that don't have a generator. One of our generous forum members sent me a diode and I made my own charger.


When I install a proper 1915 speedometer I may use the charger to illuminate it.
