Thanks Muzz!

I plan on riding this little 106 terror this summer. I am in the early stages of planning a Giro type event here in central Alberta and I think this would be an ideal bike for a couple hundred mile event spread out over a day. I am getting more and more interest in the little bikes from my fellow vintage bike gang and to plan a Giro around the small prairie towns that make up the 'Ukrainian Belt' around these parts, a myriad of small farm towns that were settled by Ukrainian immigrants from 1905 onwards.

I need help sourcing a rear brake light switch for the Gilera 106 SS, this is not a typical push or pull type brake switch

The brake light switch for this bike is interconnected to the stator ignition coil circuit, energy transfer ignition, no battery, 6V AC.

The stator coil for the ignition sends 6V AC power to the points / condenser / 6V coil from one end and the other end to the brake light stop switch. When the brake pedal is NOT pressed there is a rera brake switch connection to frame ground, this completes the ignition coil ground, when the brake pedal is pressed the brake switch ground connection is shunted and ground flows through the stop light to frame ground.

If the brake light bulb is burnt out the engine will die when the brake pedal is pressed.

The Sears parts manual lists the brake light switch as 45788. No idea if this a CEV or Aprilia unit, the stator is CEV.

I am told dome Ducati singles with energy transfer ignition (no battery) used the same system.

any help much appreciated.

I had the chance to photograph a rear brake light switch on a Sears Gilera 124 on the weekend



and I was able to trace the wire out of the stator to the switch, just one wire from stator to switch and one wire from switch to brake light. no sign of a separate ground wire to frame from the one green wire from stator.



I think I may have found one or two sources for the switch, fingers crossed this will work

The little Gilera has put up a good fight to remain dormant but after a lot of trouble shooting and repairs I got the might 106 SS to fire up on the second kick. I just could not get a spark (intermittent at best) and after disconnecting all the connections unrelated to the ignition, swapping 6V coils, high tension lead etc... I settled on the stator ignition coil having intermittent short, running an ohm meter probe across the surface would expose a short from the pressure of the probe.



I had a couple spools of fine coil wire that I never used so I removed the coil and stripped the seven windings off the frame. It ain;t pretty but I got seven full wraps and the spark is strong and steady.





Stator back in the bike, rotor torqued down, fuel bottle connected to the carb and with two kicks and just a touch of the throttle and it fired right up, hurrah! I ran a dedicated ground wire to the brake switch terminal fed from the stator to complete the ground circuit of the ignition coil.
