I have 2 cb650's.One is complete,untouched wiring.The other has been scavenged.The ignition switch is hanging from the handlebars, the idiot lghts are out of the dashboard,signal lights and tailight are gone.On that bike i want to have just a headlight with high and lowbeam,taillight and brake light,no starter button,nokill switch,2 position key just on or off or no key and just toggle switch.Coils,stator,rectifier all need wired plus the starter.Where the solenoid and rectifier would have been mounted are just wires with connectors on the ends.For a basic circuit-run a large gauge red wire from positive side of battery, to main fuse, to positive side of rectifier, to ignition switch, to positive side of solenoid.And a similar gauge black wire to the other side of rectifier,ignition,and negative of solenoid? But horn,headlights and tail and stoplights I am not sure of.I am no good at wiring as you can see.I have the tailight in a box.
