Lifan 1P56FMJ 150cc wiring help
Hello all.
I’m swapping the leaking 125cc that came on my sons pit bike from Amazon (X-Pro Bolt 125) for a Lifan 150cc (1P56FMJ). Motor mounts right up, easy peazy. Only issue is the wire harness has a lot more hook ups. My sons 125 had connectors for the kill switch, ignition coil, and the ECU. This has that and several others. (Pics to follow) If anyone can help identify what’s what I’d appreciate it. Engine model First of two cables from motor-plugs into ecu Second of two cables from engine-unknown Pink, green, and yellow connectors from ECU wire loom (you can see them in the first picture)-Unknown Yellow to ignition and 2 grounds Green and black to kill switch 2-pin connector coming off of ECU-Unknown Pink and green coming from ECU-Unknown

Perfect!
So it seems my blue plug is for a rectifier then? Can I just hook up a rectifier, add a battery, and then run 12v accessories off of it?

Depending on which stator is in your engine you can hook up a regulator/rectifier and run lights and accessories. I have a Lifan 140 on my old Trail 90 with all the lights, horn, etc., running on 12 volt regulated AC power with no battery. Where the diagram shows accessories there is regulated 14volts AC with or without a battery in the circuit. It's enough to run a 25 watt headlight and an LED tail light very brightly. |

Is that for a gear indicator, automatic transmission? Scooter?

It's for a gear indicator but some bikes just use the neutral wire. |

Well, having a problem now.
Motor is in but no spark. Checked plug and coil with swap from known working unit-no dice Checked that bike was grounded-continuity from stator to bike-good Checked output from stator wire red/black to ground-1.5V Bad stator? Shouldn’t it be 12v+\-?

Did you check for spark by holding the spark plug to a metal bolt head on the engine, while kicking it over by hand, or by touching a test light to the black/yellow wire that goes to the ignition coil, while kicking it over?

According to the diagram below, the yellow wire from the stator is coming from the lighting coil, and ties into the yellow wire coming from the rectifier for lights.

What’s the procedure for testing the 8 pin CDI?

And I don’t have a flywheel puller…yet. Besides, if I have to replace the stator couldn’t I replace it with one that supports battery charging? Adding lights and electrics to this bike would be pretty cool.
