Battery eliminator and a Newtronic ignition

I have a 1974 suzuki GT250 that I have installed a battery eliminator on...has anyone ever ran a Newtronic ignition with this type of setup? If so what do I need to do to get the job done?...I emailed Newtronic and they said that you need to have a battery, but knowing the craftiness of the people on the forum I figure someone must have tried this before

It might run if you can kick it over near red line. Seriously, without a battery there is no reserve power to trigger the ignition.

Hi!
Some GT250 motors can be started without a battery, depends on the condition of the alternator, but that's not the real problem. The "battery eliminator" is only a capacitor. This eliminates the control action of the battery and the voltage of the generator can reach values well above 15-20 Volt at higher revs, because there is no regulator. This will cause the Newtronic to emit smoke signals.

Some of the twins (T250/T350/GT250) run fine without a battery & others need a good battery.
But your GT250 uses the battery as THE voltage regulator.
My 71 T350 starts easily without a battery but then it will burn out all of the lights because there isn't any voltage regulator.
But my GT250 doesn't run well unless the battery has a pretty good charge.
You should switch to a modern rectifier/regulator if you use a battery eliminator.
How you bike runs with the battery eliminator depends on the bike-to-bike variations.

Two comments....
1) the battery eliminator is junk.
2) the Newtronics must have a 12V supply (at least mine did), ie battery. It can be a small sealed gel cell. I have a 2ah battery in my Buffalo.
In regard to the battery, using a small battery requires the charging system to work well. If your bike is 6V, get the proper battery, and I'm not sure a Newtronics would work.

Yes, and it doesn't work without fitting a battery. Newtronic aren't stupid.
