Hi I have 350lc. 4lo with a new battery kept on C -TECK charger was out last night and the bike had no electrics but started ok and ran fine on the way home the lights were very dim and would fluctuate I assume the charging system is not working any help greatly appreciated
Hi, the charging system is seperate of the ignition side so the bike will start and run fine even if it's not charging.
Usually, charging faults are caused by one of 3 things: 1) Charging coils in the stator - separate the plug and check across each pair of white wires and compare the resistances in the stator. The plug itself can often melt if the connections are iffy or corroded. 2) Wiring fault - check the other side of the plug into the loom for continuity of the 3 white wires to the reg/rec and the red, brown and black wires to ground and fuse box / battery connections. 3) Carry out a diode check on the reg/rec as show in the Haynes manual. The reg/rec is usually very reliable but I once had one where the red wire had corroded in the connector.
Good luck and if you need any more into just ask. My money is on a melted stator plug!
You can get replica plugs for the 3 white wires, or if you are not fixated on being 100% original, you could fit something different with better connections.
