Question After wash, front signals solid and rears quick blink

Hey all,

I have a 2015 FZ-07 for which I have done some extensive lighting mods to. This includes front & rear LED signal swap, splicing the rear signals to add additional LED strip signals on the side (now removed, but splicing connectors are still there), and a custom dual headlight setup. All of these have done myself with questionable quality lol (first real foray into soldering/electrical).

I have a problem now and I don't know where to start to diagnose it. When signaling, my front signal remains solid on. The back one flashes at about a rate of 150 flashes/second (faster than the typical "malfunction flash").

The signal buttons still trigger the correct indicators. The hazard lights still correctly trigger all signals, but just with both fronts solid and both rears quick flashing. Everything else (headlight, horn, instrument display, brakelight) works fine. I DO have a custom/aftermarket signal relay that was working great to regulate the signal speed.

I washed my bike last night and this morning I discovered this problem. The bike has had plenty of time to dry out at this point.

Where do I start looking to fix?

get out your air nozzle and blow all connections clean. pull them apart and re grease them with Dielectric grease..

If the hazard relay works fine then it must be your signal relay. "Custom" rarely means weatherproof :-)

Also, love your headlights. Where did you get them and hows the light pattern?

I didn't use dielectric grease initially... hope that isn't a problem. I will give your idea a shot though.

I edited the first post. The hazard switch triggers all lights, but they are still both solid in front and quick flashing in the rear. The signal relay is pretty covered under the left body panel. I don't think that is the problem because I have washed it plenty of times before since I've had it with that relay.

And here is a link to what I did for the headlights with some links to products there. Beam pattern for the "Dominator 2.0" is different but not worse than stock, so it is good enough.

I would start with the ground(s) they are most likely to be effected by moisture and corrosion. Loosen and move the switch on the bar. Then check the grounds are clean from the problem lights. If that fails the flasher/relay may have just been ready to go and the moisture could of been the straw that broke..... good luck.

Start troubleshooting at the front signals. Disconnect them one at a time and see if the rears and/or the front signal that is still connected flash properly. If disconnecting either the fronts makes no difference - you guessed it - try the same method on the rears.

If the problem doesn't appear to be right at the lamps you will need to work your way along the wiring back from the lamps to the relay, looking for a short.

"Custom/aftermarket signal relay" - solid state? Adjustable flash rate?

Thanks for advice all. I noticed when I got home that the fronts appeared to be flashing as quickly as the rears, it was just harder to identify so they appeared solid at a glance. Since both are flashing quickly, I bet it is the
relay.

I ordered a new one, but first I am going to try your guys' advice of disconnecting everything 1 by 1 first. Then I will put in the relay and re-insert everything 1 by 1 and see if that fixes it.

It seems to have a large following and lots of positive reviews.

Wtf

Well, to make things even more confusing, 3 days after the problem started, it solved itself. Last night I was installing LED underglow lights on my bike which involved unplugging hte battery a few times. This morning I start up for the ride to work, and the signals are back to normal flash rate & operation.

Timeline of events:
  • Sat 10/8 - signals are OK
  • Sun 10/9 - Washed bike
  • Mon 10/10 - discovered signals were solid in front, quick flash in back
  • Tues 10/11 - The front signals are now flashing quickly like the back
  • Wed 10/12 - signals are OK again

So it is like I got something wet in the wash and maybe that was causing something weird with the circuit. As the days went on and it "dried" out fronts went from solid --> quick flashing --> normal. I have no idea if this is plausible or why this happened lol

Would go through all the connections and apply dielectric grease. That way there will be less of a chance of it happening again.

I used to have a truck that would lose the dash lights every time it rained. Turns out the inner cowl was rusted though and leaking water. Sealed it up and it never happened again.

Looks like that relay should work fine. Tape up your connections and you'll probably be good to go.

Just a guess: Water created a short and bypassed the resistance of your flasher/relay.

FYI

I had a dry bike with the signals running fine. I sprayed the back for a few minutes. No change in signal speed. So it must be the front.

I sprayed the front. After a few minutes, they blink fast again. That confirms my suspicions.

I had the new relay I ordered. I plugged the new one in. Even with the front soaking wet, with the new relay it flashed a normal rate. So maybe my older aftermarket relay was just going bad? (though it had only seen about 8-9 months of use). I hope these don't need replacing every year. Not too big of a deal since they are only $20 but a little disconcerting.

Maybe the water is accelerating the rate at which they fail?

Maybe the aftermarket one was not as waterproof/weatherproof as the factory relay.
