If you still don't have spark, the problem is not in the wiring (unless it's in the wiring of components under the flywheel). If you have spark now, and you didn't before, you know the problem is with your wiring (most likely with your black kill switch wire or with the blue/black horn wire). Ground all other wires coming out of the stator, and also make sure that your coil is grounded. If you JUST want spark - no lights, no other electrical components - then run the blue wire from the stator to the blue wire going to the coil (disconnect the black wire).

Sometimes you have spark problems, and you want to make sure that the problem isn't with the wiring. Puch Premium Wiring:12v lights, horn & blinker wiring Wiring for Spark ONLY Puch Wiring Video upgrading to 12v lighting & turn signals without external battery source. The yellow to the headlight will usually be hardwired on, although you could keep the speedo bulb and light switch if you really wanted to.Ī full image for a hardwired and no-brake-lights system would look like this:Ī step-by-step tutorial for this setup can be found here This wiring block does not have the horn or brake lights hooked up.

This diagram disables the horn, light/horn switch (light is always on), and the speedo bulb.

It's a good idea to check local laws before hardwiring your moped, because many states or municipalities may require safety features like a horn or brake light, and removing them would make it technically illegal to ride. It also makes troubleshooting electrical problems much easier because you will already be familiar with all of the wires and their purposes, and because there are fewer wires that can become broken or disconnected. This can make the wiring appear neater by allowing for the removal (or shortening) of the wiring block, by keeping switches and wires off the handlebars, and by reducing the total number of wires. Often, people will simplify their wiring to remove electrical components that they deem unnecessary, like the horn, speedo light, kill switch, brake light, or turn signals.
