sparkling braker

Post by sadek » Sun Dec 02, 2018 10:09 am



Hello everyone,

I'm fresh in motorcycle mechanics so please for leniency. I had bought about one month ago gl1100 from 1981
with swapped carbuetor and ignition from gl1000. Problem is the ignition, is not smooth as should be.

First what i have done is change coils for the chrysler neon's one because of wrong resistance of the oryginal but nothing change.

There was no ballast resistor so I bought new one, install and now it's smoked, but why it happened?

Capacitor is ok, it's working the same in the old and new one.

Gap in the breaker looks ok but there is one thing i'm wondering - the sparkling in the braking points , is it normal ? thanks a lot.

Here is video :

The Neon coils are very low resistance (about 0.6 ohms). The original coils are 3 ohms. By using the Ballast resistor with the Neon coils, you are passing much more current through it than it was designed for, which is why it smoked. Using the Neon coils without the ballast resistor you are pulling 20 amps through the breaker points so they will definitely spark!
Unless someone on here knows different, the Neon coils can't be used on GL's with points. You could use them if you put resistors in series with each circuit, but they would have to be very large wire-wound ones, capable of passing high currents and dissipating plenty of heat and, by adding the resistors, you would end up with a similar resistance in the ignition circuit to the original coils and therefore, little or no difference to the spark at the plugs.

I just recently put a neon coil on a 1000 with points. I added the ballast resistor from an 1100 (1.5ohms) and put a relay in the ignition circuit. It actually drew less current than the original coils. Worked real well. sadek, you can't run that setup without a ballast, all that sparking is a sign of too much current to the points. The resistor you bought just wasn't heavy duty enough. Wondering why someone would replace the very reliable 1100 ignition with that.

Me too wondering why, anyway I'm waiting for original coils that I bought on ebay. Hope they will work well. So you say gl1100 should has also ballast?

82-83 1100s have a ballast, 80-81 do not.
