Exclamation Nightmares

Okay, so I'm new to the RC-51 scene as I have recently purchased a 2001 RC-51. I'll tell you what, I will never want another bike again. I absolutely love this bike!

I am having a very upsetting problem though. Where I live, you are required to have working turn signals to pass state inspection. The RC-51 came with an aftermarket under tail which looks amazing.

Problem:

1. None of the turn signals work. No running lights etc.
2. The turn signal indicator in the dash is not blinking amber like it should.
3. I can't figure out what the problem is because everything is wired the way it should be, no burnt out bulbs, etc.

Actions taken so far:
I unplugged all of the turn signals and clicked on the turn signals, left, right, and off.
I got a faint response from the indicator on the dash, and I'm still hearing the relays kicking over. (A faint flicker of the indicator lighting up for a mere second then quitting.

UPDATES:
-I am now getting a steady indicator light on the gauge cluster a long with a buzzing noise coming from the relay.
-I've tried wiring my headlight bulb up to it each turn signal with no luck, just the same response from the bike when I hit the turn signal, no indicator light, no turn signal.
-I have LED rear turn signals, and bulbs for the front.

Does anyone have any suggestions of what the problem might be or what I could try?

I want to get out on the road as soon as possible but this is the only thing holding me back.

Thanks in advance.

Brad


P.S. Some of you were asking for a picture of what the ass end looked like so I found the same exact under tail on the net. Posted Below.
Will have a video up tomorrow at some point.

EDIT: I can't post images until I get 10 posts. :l

To start I'd...
Check the voltage at the lights
Bench test the relays
Make sure the switch is making good contact.

I'm sure someone will be a long shortly with the link to the PDF service manual.

Double check all the grounds and look for corrosion and all connectors and apply a little dielectric grease to them

Posted originally by Sub. After double checking all the wires (to ensure they are correctly wired)...I would check the relay again. Are the blinkers LED? People forget to change to an after market relay when changing lights.

Brake/Taillight:
Green/Yellow = Brake Light
Green = Ground
Black/Brown = Tail Light

License Plate Light:
Black/Brown = License Plate Light (same electrical point as above)
Green = Ground

Left Rear Turn Signal:
Orange = Signal
Green = Ground

Right Rear Turn Signal:
Light-Blue = Signal
Green = Ground

Front Left Turn Signal/Running Light:
Orange = Signal
Orange/White = Running Light
Green = Ground

Front Right Turn Signal/Running Light:
Light-Blue = Signal
Light-Blue/White = Running Light
Green = Ground

2001 SP1 (sold)
2004 SP2 (properly stored)
2012 Ruckus (stolen)
2015 Grom (under construction)

Haha, alright.

Well here's what I found so far. What the previous owner had going on in the tail section was a birdnest so I tidied everything up a little bit. The blinkers for the tail light are LED. The front blinkers are the tiny little orange bulbs inside of a housing case. I unplugged ALL of the turn signals and flicked the turn signal on and I got the indicator light working (Solid, not blinking) on the gauge cluster. Also a buzzing coming from the relay. As soon as I would plug a turn signal in, it'd stop and the light would go out. I tried this with all four of them, one at a time. I even went as far as to take my headlight bulb out and try that with one of the turn signal wires. Same thing, no blinking, no nothing.

Any other suggestions?
I will get pictures up tomorrow at some point. Or even make a quick video explaining and showing what is wrong.

Thanks again.

Nice that you like the RC51 so much.

Buy yourself an LED indicator relay from Ebay (2 connector type that is a direct replacement for the original). I would suspect it's that, since a standard relay won't work properly with LED's due to incorrect load / resistance. Let us know how you get on so that if it is this, others will know from searching in future. HTH

And completly tidy up that bird's nest. Sadly it's a common problem with undertail conversions, but there are tidy ways to sort it out. If not, you may have more electrical problems in future...

Solder, shrink wrap and dielectric grease are your friends here....
