Ironhead another minimalistic wiring diagram

[scottericsonon]

well one of the things i'm planning to do to my bike this year is re-wire it...........

theres a couple burned spots in my harness and some P.O repairs that aren't real pretty....

plus i want to clean up that rats nest inside the headlight

so i drew up this little diagram that someone else may also find useful........

i plan to print it out and keep it inside a ziplock baggie in my tool kit "just in case"

you will need a diode in your gen light circuit

[scottericsonon]

where at russ? i hadnt seen one in my manual........

all i saw was one side going to 12V and the other going to the genny

[russzx6]

I think they are in the headlight nest in a stock harness, they are just inline, see post #22 here and pick that part out, you need to make sure the diode is around the right way. What your aiming to do is allow power to flow one way but not back from the battery the other way, the light will glow when it picks up a difference in voltage on both sides of the diode

The diode should be in the headlight bucket, placed in series with the gen indicator light, or in a wire going from a 12 pin to 6 pin plug, possibly an orange wire. Part #74563-65. Make sure it's taped up good or use a heat shrink.

fixed with the diode...........


should just be a standard 1n-4004

thanx for the heads up

diode isn't shown in my service manual OR my parts book

i must need new glasses because im STILL not seeing it,,,,,,,,,

ive hilighted all the relevant wires here

In my 70 to 78 FM it does not show up in the diagrams until 1978. Then it is number 49, left side of diagram, inside the headlite housing dashed line.
