Turn signal broken and i am confused

[GTi Giant]

Ok, on my aspy in the left rear turn signal is not working. I have checked it, and it is getting the same level of current as the right signal. I have replaced the bulb, not working. I have taken the bulb from the right light (i know it works) and put it in the left. Not working. Any ideas? I am confused at this point.

Place the + side probe of a voltmeter on the + contact inside the bulb holder and the - side to ground.

Are you reading 12 V

Place the + ohm meter on the ground side of the bulb holder and the - to ground

are you reading continuity?

I didn't get a chance to check continuity, but this morning before work I tested the right and left bulb sockets.

I am going to upload pictures here in a bit of the socket style as well.

Right (working) socket:
2.5 to 4.7 volts (sin wave variance)

Left (not working) socket:
1.3 to 3.7 volts (sin wave)

This is with a digital multimeter with the turn signal turned on for the appropriate socket.

pictures. sorry they are bitmaps, i'm an idiot and didn't save them as jpgs.



the wire that is wrapped here was "cut" upon the initial install, i was afraid that it might have been touching something so I taped it up to remove it from the equation. They only used one socket type across the bike it appears, regardless of how it was going to be used.

I presume we are talking 85 Aspencade here. If you look at the schematic the left bulb it is Green and Orange wiring. I see that your wiring is blue or purple and green ? The green is ground and connected to the rear brake and tail light. Assuming you have continuity to ground that should be OK. Tracing the Orange wire on the schematic it connects to the front left flasher and the flasher indicator in the dash and the turn signal switch.
The socket using two pins would require a bulb with two connector points, one for + and one for ground, the ground wire on your socket is connected to the outer portion of the socket.

What is the base of the bulb your using?

Something doesnt jive, is the socket your using an add on or a fix?

[GTi Giant]

it is a stock setup. It is a two feed bulb socket with a the ring ground. And no, the colors do not match up with the Clymer wiring diagram. I am using a 2 feed bulb in the socket and and have used the bulb from the right light and it still does not work. I agree, not jiving appears to the be the name of the game here.

Then it is the wrong socket.
This is the socket from the left side on my bike and I have had it since new, Dont even think I replaced the bulb yet

The bulb you should be using is a 1073 12 v 23Watt single pin single contact.


The wire that is cut off probably goes to one of the contacts, trace the other one and make sure it connects to an orange wire further up stream and solder the two connectors in the holder and make them one.

Or you use the two wires ( the one you cut and the other one coming from the socket) join them together they should go to an orange wire then you will be using both filaments in your bulb... super bright signal light.

very very interesting..... The other line that comes into this socket (the one that was "factory cut") is a solid power always on feed, which explains why it is not connected.

As for the harness this bulb (and the running/brake light) plug into, it shows me the same current readings the bulb socket itself does, so I don't think the socket has anything to do with it as both the left and right are the same and they both used to work.....

When you take off the whole lower section there are two holders, I never tried interchanging them, one is the brake/tail light this has two wires and a ground the turn signal is just one wire and ground.

I doubt it's factory wiring or at least Honda factory wiring, I would start tracing back.
Under the seat there are two rubber covers one on each side there is one four pin connector in each one, they should be the same as the schematic in the earlier post.

Possibly the PO did some other wiring, I dont see where this always on wire is coming from. Is it live all the time or does it come live when the IGN is switched on?

The brown wire is tail/license wire
Green/Yellow is the brake
Light brown is right signal
Orange is left signal
Greens are ground

[GTi Giant]

Once again I bow before thy great and vast knowledge

The PO did a great job on the wiring and selecting the connectors everywhere except up in the harness under the pillion. IjioT!!!!!! I found the broken <read here spliced wire, that was not taped/soldered or anything together> wire in the shrink wrap cover. But I know eveb more about my bike now. I got that all trouble shot and should get that part all fixed tomorrow.

Tricky for prez!

Glad you got it figured out.
