I don't know what kind of set-up they use. Is the battery cables going thru the key switch like on a Speedex?  Those old switches go bad when setting around long time and in weather.  I put in a selinoid system so big current does NOT go to the key switch and only light juice to the selinoid to attempt the starts.  OR, do you have the BIG push start button like on old, old tractors? I say just replace that, but get a good one, and maybe clean all the battery cable ends there and at other places they go to.

Big push button starters on the L models, foot activated.


As Gary mentioned, if the smoke is definitely coming from the actual switch; it's time to clean up the contacts and see if that helps. If not, replace it. I would also check the wires over well and replace or repair as necessary.

How does the starter look? Feel comfortable opening up for a good inspection and cleaning?

Anything electrical that has already had the smoke let out of it needs to be replaced.   Its been too hot and is burnt internally. 

There is too much current going through the switch, or there is resistance in the switch.   Resistance builds heat. 


Earlier "L's" had 6 volt starters.  Check to make sure you aren't running 12 volt through a 6 volt system. 


Where's my manners?   :welcometogttalk:

Welcome aboard, just smoked my Springfield at a show a couple months ago, I quickly turned the key to off but to no avail, melted the wires looked like a forest fire. New ignition switch, regulator and wires cured it.

Agree with the above. Also don't hit the starter button and hold it for very long, 10 seconds or so at a clip. If you hit it more than a few times let it rest and cool down, The L will start pretty quick or it won't. If not then somethings not quite right. dirty points or carburetor or a bad condenser are the usual suspects. 


Oh and welcome aboard!

Thanks for all the information.I need to find out if this is a 6volt or 12 volt system .Model No is J110529. Going to clean up points soon as weather cools off. Thought motor had a stuck valve but after taking head off it seems to have just been stuck.Looking forward to getting this thing running again.Thanks Robert
