DYNAMO WIRES

[fatboy98]

HELLO TO WHO EVER IS STILL ON HERE . I HAVE A QUESTION ABOUT THE THREE WIRES THAT COME OFF THE DYNAMO. WHERE DO THEY GO TOO. ANY HELP WOULD BE APPRECIATED.IT IS A 1967 SCRAMBLER.

Lots of us still out here!

The three wires from the dynamo simply connect into the wiring loom at the rear of the engine adjacent to the main frame tube.

Beyond that you really need a manual or at least a wiring diagram, I think you'll find the latter somewhere on the site.

From memory, the brown wire goes direct to the rectifier, the yellow wire also goes to the rectifier with an internal connection in the wiring loom also going to the lighting switch.

The pink wire goes direct to the lighting switch.

When the headlight is switched on a connection within the lighting switch connects the pink and yellow wires together sending the full output of the dynamo (actually an alternator) to the rectifier.

When the headlight is OFF only the yellow output wire is connected to the rectifier, the brown wire is 'common'

THANK YOU DJM. WOULD THESE HOOK TO THE GROUP OF WIRES WITH THE REAR BRAKE SWITCH WIRES HANGING OUT OF IT? IT HAS A BLACK RUBBER SHIELD AROUND THEM?THANX AGAIN.

[DJM]

Yes, you should find three matching coloured wires under that rubber sleeve, wires from the engine side have 'male' connectors or bullets fitted which fit into matching 'female' connectors on the wiring loom.

Also there you should find a light green wire with a red stripe which comes from the neutral switch on the engine.

If the wiring has survived the last fifty-five years without damage, the neutral light wire mentioned above should be inside a black oversheath from the engine along with the pink, brown and yellow dynamo wires.

Good Luck.

YES IT IS IN THERE AND IN REAL GOOD SHAPE.DO I HAVE TO PUT A LITTLE EXTENTION WIRE FOR THAT SWITCH TO REACH THE LOOM?

[DJM]

If everything has survived intact the wiring from the 'engine' end should long enough to hook into the wires under the rubber sleeve.

If the wires have been damaged or shortened then, yes, you will need to repair / extend the wire from the neutral switch to connect into the loom.

To check everything is as it should be, if you ground the green/red stripe wire under the rubber sleeve the neural light on the headlight should light up,

Pretty straight forward, typical of 60's Hondas.
