6v to 12v conversion honda c90

[Alex_]

Hi there I had been told this was possible to change this engine from 6 volt to 12v?

The engine is on a go kart so no need for lights etc

Anyone done this? And what materials do I need

Thanks for looking

sorry should of said, my wiring is in such a mess. im not getting a spark on it. rather than buying a replacement loom i thought it would be cheaper doing it this way as thats all im after, ignition.

hope that makes sense. cheers

Changing it from 6v to 12v won't get you a spark if your wiring is a mess, best to rip all the wiring out and do it from scratch with just the wires you need. Once the lights and horn are ignored, there's very little left.

hi again, i was told i could rig up he 6 volt battery to my wiring the way it is, sorry im not good at reading diagrams so anyone able to tell me what wires i join to the battery?

You need the red wire on the coil to go to battery +ve and the green wire on the coil to go to the points under the cover.

You also need to make sure there is an good earth (battery -ve, engine, coil) and it would be best to add a kill switch (aka, a loose bit of wire connected to the coil green wire which you can touch to the battery -ve to stop the engine)

Finally, you need to make sure you have the thing marked "capacitor" connected between the coil green wire and ground.

Battery won't charge but engine should run.

no wires on this make any to any diagram i can find, i purchased a second hand coil from a c50(are they the same?)

cheers

Ok, coil should have two terminals on it, hopefully marked "+" and "-".

+ goes to the battery +ve. convention says this wire is red.
- goes to the points and to the capacitor and also go to your kill switch. Usually all 3 are green wires.

Then everything needs earthed. should spark!

No markings = trial and error

no mate this one doesent just one wire black and white, i thought the c50/c70/c90 6 volt coil were the same?
