Cb400 four indicator wiring

(1/3) > >>

Dolomite_:
I have a few issues with the wiring that I just cant get my head around so wanted to see if anyone has had any similar problems. The indicators arent working. There is voltage on the black and gray wire going out/in the indicator repeater and im getting a voltage reading on the gray wire at the switch on the bars but when I flick the switch to left and right I lose the voltage. The headlight and brake light turn on so I know the wiring is working.

Nurse Julie:
Have you got all the wires earthed (green wires) correctly through the earth tabs each side on the inside of the headlamp bowl?

I'm guessing the indicators are aftermarket as they dont have an earth wire coming out of the indicator housing so they are grounded at the end of the indicator storks where I have took some paint off.

Ah, OK. I have never had any dealings with aftermarket indicators so I'm no use to you at all then. But, I'm sure they need to be earthed correctly to stand at least half a chance of working.

PatM:
One wire?- well, they must get their earth return from somewhere. Id put one of the indicators across a 12v supply to find out where. Also, if they are LEDs- that can throw up another conundrum (they only allow current to pass in one direction as they are diodes) . You might have to put your own earth returns in and connect up. Case to frame connection is notoriously troublesome.
I glad Julie knows the wire-colours of the rats-nest in the headlight bowl!

Side comment- Not much bike-riding going on in kent today..just had hailstones...Spring will come, but no sign of it this weekend- bikes to ride, bikes to polish...
