Turn Signal fuse pop's constantly, how to diagnose?

[djbordie]

Been riding with the relay/stebel for a good 2 weeks now.

Sunday bike was out in the sun for 8-9 hours, parked.

Now every time I click my turn signals or 4 ways it pop's that fuse.

How do I go about diagnosing this issue? Is there some way of "tracing" the path?

I have checked all wiring from the stebel install, its fine. nothing has "melted" or is exposed. But that is on a different run anyways...couldnt see how it would effect the turn sigs.

thank you

ive got a 25 amp fuse, can i just put that in place of the 10amp fuse? considering the blinkers arent used as much as say running lights?

or is that asking for a disaster...hah

That the fuse pops when you activate the turn signals means the fault in the circuit is not upstream of the switch, it has to be either the switch itself or something downstream.

Unplug the turn signal relay and see if the fuse still pops. If it does, the problem involves the switch or the wiring between the switch and the relay (inspect carefully for worn insulation, etc). If the fuse stays okay with the turn signal relay unplugged, then unplug or remove bulb from all four corners, and re-install the signal relay. If the fuse pops with the relay installed but all bulbs disconnected then the problem involves either the relay or the wiring between switch and relay. If the fuse stays okay with it like this, then the problem involves one of the bulbs or wiring to it.

DO NOT do this. You could fry your whole electrical system this way.

Does the fuse fail when you use the right indicators but not the left? If so, the fault is probably in the wiring related to that circuit. It could be a short to ground in the bulb holder. If the fuse fails whether you choose left or right signal, the fault could lie within the circuitry common to all signals, as suggested, ahead of the flasher relay or turn signal switch. Places to look are the wiring as it transitions around the headstock (maybe worn insulation) or at connectors related to the left handlebar controls. The quickest way to diagnose this problem is to have a multimeter, so that you can test resistance, voltages and continuity.

ACTUALLY! yes.

i click right, its ok. left it pop's.

Brian: is there a relay on stock signals??

Is there any way of testing all this without going through a box of fuses? lol...

The turn signal relay is the thing that makes them flash ...

But if it only pops the fuse on one side, that isolates the problem even further. Check the bulbs and bulb holders on that side. Might just be a bad bulb.

aftermarket LED's on the front and rear. (no aftermarket relay needed)

so I cant even open or check them...arg.

but the insulation looks fine on everything

TRACE wires back to see if you have a bad ground or shorting issue, use a multi meter!

put in a 15 amp fuse to test with...and it didnt blow...everythings fine now....WTF

so ill put in a 10 after i buy some and see what happens.

honestly i hate voodoo electronics

 

[djbordie]

SO WTF

it must be a negative wire shorting on the left side, only when its in the perfect position. (im guessing insulation is stripped somewhere...)

i put in the proper 10amp, and rode away like nothing happened.

have plenty of extra in the tail now, just incase. im sure the issue will surface again

 

[robmack]

Intermittent electrical problems are difficult to isolate and fix. You're right; the problem will probably resurface again.

I would hazard a guess that the problem is an exposed terminal shorting to the frame. This could be under the tank where the left cluster connector is located (loose ground wire???) or within the left signal stalk. When you get a chance examine those areas carefully and treat any exposed terminal or wire with suspicion.

Sounds like a ground fault. Double check the wiring for any wear or exposed bits.
