Hey guys! I was just working on my old Cub 102, and I got her to run. But, the coil gets REALLY hot, and I just drove her like a few feet, and she died. It doesn't smoke, but I think the carb is a little iffy still on her. But, the wire going from the coil to the points is pretty bad, and the negative termenle  and looks like its melted a little. I say it would need to be re-wired. What do you guys think? Thanks Ian!

Sounds like either the points are grounding out or the condenser is FUBAR..  

 

Unhook the Coil's - (negative) wire and separate the condenser from the points wiire.  

 

Test the points wire to Ground or the engine block with a continuity tester or OHM meter.  Rotate the engine slowly with the key OFF and it should be totally open or no continuity when the points are open.  If they are always grounded the points or wiring is your problem.  Repair or replace.

 

If everything is OK with them check your condenser with an OHM meter..  It should start with continuity then it should fade off (I believe-  not sure-  it's been a while)  I'm sure someone else will straighten me out.  

 

If life is OK there check the Positive voltage supplied to the Coil's (+) terminal to ensure it's not overcharging the battery and is over ~14 V DC..

 

Hope this helps!

If that coil is getting real hot, it's probably time for a replacement. Checking everything else would pin it down, for sure. But it sounds to me like the coil is the main culprit here. Got another coil you could swap in to be sure?

I suspect that the coil isn't the correct one. 

Some coils need an external resistor, it would be simpler to find a good 12v coil and replace it.

Check to see how many volts is at the wire going to the coil. If the voltage is way too much a new coil could get burnt also.

 

Then your trouble is that the regulator isn't working.

I agree with Arti . If its got the wrong coil it will run great for a while , but won't last very long and the coil  will get hotter than .....heck .

I'm speaking from experience as I had a 104 once that had the wrong coil on it when I bought it .

Thanks for the help! I took a muiltimeter and I checked if the battery was charging, and it is. The points seem to fine and gapped correctly, but will check! I would say its the coil,but will do some test! Thank you again!!! Ian.

Will do some test and swap coils and check! Thanks! Ian

Yeah, I don't think its the right coil either. Thanks!! Ian.

I did whip out my muiltimeter when it was running, and the battery is charging. I know its not the voltage regulator. I may need to replace the coil. Thanks!! Ian.

I agree too, and plus I took my Cub 122 out, and towed it to the shop and I felt my coil and it wasn't hot at all. I will check the coil. Thanks for the help!! Ian.
