Simple puch wiring diagram - On occasion you have got spark issues, and you want to make sure that the problem is not with the wiring. If you simply want spark -- no lights, no different electrical additives -- then run the blue cord from the stator to the blue wire going to the coil (disconnect the black cord). Floor all other wires popping out of the stator, and also ensure that your coil is grounded. If you have spark now, and you did not before, you understand the trouble is together with your wiring (maximum in all likelihood together with your black kill switch twine or with the blue/black horn twine). In case you still do not have spark, the trouble isn't in the wiring (until it's within the wiring of additives beneath the flywheel).
Critical word: the inexperienced/red (no longer proven at the diagram that is in any other case accurate) and the yellow wires leaving the magneto have to be twisted collectively and positioned into the terminal block collectively. The wire maintains as yellow most effective. The other twine shades assembly on the terminal block are black to black and grey to grey.
Regularly, human beings will simplify their wiring to eliminate electrical components that they deem unnecessary, just like the horn, speedo light, kill transfer, brake mild, or turn indicators. This could make the wiring seem neater via bearing in mind the removal (or shortening) of the wiring block, via maintaining switches and wires off the handlebars, and by lowering the entire variety of wires. It additionally makes troubleshooting electrical problems plenty easier due to the fact you will already be familiar with all the wires and their functions, and due to the fact there are fewer wires that could grow to be broken or disconnected. It's a very good idea to check local legal guidelines earlier than hardwiring your moped, due to the fact many states or municipalities might also require protection capabilities like a horn or brake mild, and doing away with them might make it technically illegal to journey.
This wiring block does now not have the horn or brake lighting installed. The yellow to the headlight will typically be hardwired on, although you can hold the speedo bulb and mild switch in case you truly wanted to.
